Abstract

We present the spectroscopic characterization and laser operation of a 2%at. Yb doped Gd3(Al0.5Ga0.5)5O12 (Yb:GAGG) crystal, grown with the Czochralski method. We determined the absorption and the emission spectrum, the upper level lifetime, and the thermal conductivity. The internal disordered structure determines a significant broadening of the emission band (12.1 nm FWHM) with respect to the parent composition Yb:GGG (8 nm FWHM). The laser performances were evaluated on an end pumped cavity, using a CW semiconductor laser as the pump source. We obtained a maximum slope efficiency of 60.8% and an optical to optical efficiency of 46.0%, with a maximum output power of 4 W, limited only by the available pump power. The tuning range extends from 995 nm to 1050 nm. To our knowledge this is the first spectroscopic investigation and the first assessment of the laser performance of an Yb:GAGG crystal with this composition (i.e. Al/Ga balance = 0.5/0.5).

1. Introduction

Among crystal materials, garnets are the most widespread matrices used as laser host for rare earths dopants, due to a favorable combinations of parameters: ease of growing in large size, broad transparency range, good thermomechanical properties, compatibility with several trivalent ions as lasing dopants, such as Nd, Yb, Er, Ho, Tm, Pr. So far, several garnets have been proposed, YAG, LuAG and GGG being the most diffused.

Recently, the so-called mixed garnets, i.e. solid solutions of garnets with different compositions, have been proposed because the internal disordered structure may induce an inhomogeneous broadening on the absorption and emission spectra of the lasing ion. This feature is advantageous in particular for the generation and the amplification of ultrashort laser pulses. Several compositions, suitable for Yb3+ doping, are reported in literature. Partial substitution of the trivalent ion was used in (LuxY1-x)3Al5O12 i.e. LuYAG (both crystals [1] and ceramics [2,3]), in ceramic (GdxY1-x)3Al5O12 (GdYAG [4]) and in crystalline (LuxGa1-x)3Al5O12 (LGGG) [5]. Partial substitution of the divalent ion was used in ceramic (Y3ScAl4O12) [6]. Both the divalent and the trivalent ions were partially substituted in ceramic {YGd2}[Sc2](Al2Ga)O12 [7].

Gd3(AlxGa1-x)5O12 doped with Ce3+, (GAGG:Ce3+) [‎8,‎9] was initially proposed as a scintillator. Spectroscopic studies on Yb-Ho and Yb-Er doped GAGG were recently reported [10,‎11], as well as CW [‎12] and mode locked [13] lasing of Nd:GAGG with various Al/Ga ratios. Concerning Yb:GAGG, CW [‎14] mode-locked [15] and Q-switched ‎[16] laser emission were demonstrated only for the ratio Al/Ga = 0.1/0.9 (Gd3(Al0.1,Ga0.9)5O12) with 6.2% Yb doping. These previous investigations indicate that GAGG can be a very interesting laser host for Yb: the disordered structure induces a significant broadening of the emission band [‎14], but at the same time it does not degrade dramatically the thermal conductivity in comparison with other pure garnets (see for instance [‎17]).

These reasons motivated the interest for the study on other GAGG formulations with higher Al/Ga ratio, i.e. Al/Ga = 0.5/0.5, to assess the impact of this parameter on the Yb spectroscopic properties. Moreover, due to the significantly reduced content of highly volatile gallium oxide in Yb:Gd3(Al0.5,Ga0.5)5O12 with respect to Yb:Gd3(Al0.1,Ga0.9)5O12 it is expected that its composition is less affected by the loss of Ga2O3 during the growth. Finally, owing to marked difference of ionic radii of Ga and Al, the creation of antisites would be reduced, resulting in a crystal structure with low defects concentration. We present the first spectroscopic investigation and CW laser performance of a 2at.% Yb doped Gd3(Al0.5Ga0.5)5O12 crystal finding a maximum output power of 4.0 W, with a corresponding slope efficiency of 60%. Finally, we explored the tuning range, which resulted to be 54 nm, i.e. from 996 nm to 1050 nm.

2. Sample growth and properties

The sample was grown by the Czochralski method using a Malvern MSR4 puller with an automatic diameter control based on weighting the crucible. Starting materials (Gd2O3 (4N), Al2O3 (4N5) and Ga2O3 (5N)) were dried at 1000° C for 4 hours before weighting. Powders in appropriate molar ratios were mixed to obtain desired stoichiometry. Suitable amount of Yb2O3 (4N purity) was introduced in place of Gd2O3. Powders were pressed into a cylindrical pellet at 200 kPa and calcined at 1350° C for 6 hours before melting in a crucible. Single crystal was grown under N2 atmosphere on <111> oriented seed (pulling rate of 2.5 mm/h, speed of rotation 20 rpm). Transparent crystal with 20 mm diameter and 50 mm in length was grown with a convex crystal melt interface from inductively heated iridium crucible of 40 mm in diameter, see Fig. 1. The doping level of Yb3+ was 2 at.% (2.54x1020 ions/cm3).

Phase analysis and structural refinement were performed on the powdered sample with a Siemens D5000 diffractometer (Ni-filtered Cu Kα radiation). Data were collected in the range 20°-100° (step of 0.02°, averaging time 10 s/step). The powder diffraction patterns were analyzed by the Rietveld refinement method using DBWS-9807 program [‎18] in order to determine the lattice constants. Rocking curve and 2Θ scan (Fig. 2) were recorded using the same diffractometer on (100) oriented single crystalline plates (step of 0.01°, averaging time 10 s/step). From these measurements the lattice constant resulted in a = 12.231 Å, as it is shown in Fig. 3.

Figure 4(a) reports the absorption cross section spectrum (σabs) measured with a Varian Cary 5E spectrophotometer (bandwidth 0.5 nm). The absorption spectrum features a broad band between 905 nm and 945 nm, peaked at 943 nm (peak σabs = 0.91 × 10−20cm2), well suited for pumping with semiconductor lasers. The zero-phonon line is located at 970.3 nm, with a peak value of σabs of 1.18 × 10−20cm2. The absorption cross section here is higher, but the relatively narrow width of the absorption peak (about 3.4 nm FWHM) requires a tighter wavelength control of the pump source.

The absorption spectrum recorded at 5 K (Fig. 4(b)) shows that the zero phonon absorption line has a single peak structure, with a FWHM of 1.27 nm.

The lifetime of the Yb3+ level 2F5/2 was measured with two independent methods, both aimed to minimize radiation trapping effects: on a finely powdered sample (obtained by mechanical crushing of a bulk sample) and on a bulk sample by means of the so-called pinhole method [‎19] using the experimental set-up described in [‎20]. As it is known [‎19-‎21], the reabsorption of the emitted fluorescence lengthens the fluorescence lifetime with respect to the upper level lifetime. Both measurements techniques resulted in the same value, 0.91 msec. For comparison, the fluorescence lifetime on a bulk sample without pinhole resulted in 1.1 ms, with only about 20% increase owing to the low doping level of the sample.

Luminescence spectrum was acquired by Dongwoo Optron DM711 monochromator having a focal length of 700 mm, coupled with an InGaAs detector. The measurement was carried out on a finely powdered sample, so as to avoid reabsorption effects: due to the small size of the powder grains, the emitted photon has a low probability to be reabsorbed before to leave the grain volume. The emission cross section spectrum was obtained from the luminescence spectrum using the Füchtbauer-Ladenburg formula. The emission cross section spectrum (σem, see Fig. 4) has a peak value of 1.83 × 10−20cm2 at 1027.0 nm, with a FWHM of 12.1 nm.

Thermal conductivity was measured by the steady-state longitudinal heat-flow method. The crystal, in the form of rod 10 mm long and 3x3 mm2 of cross section, was mounted in a temperature controlled liquid He cryostat. The temperature drop along the sample did not exceed 0.2 K; extreme care was taken to eliminate parasitic heat flow between the sample and its surrounding. The thermal conductivity at room temperature is 8.1 ± 0.6 W/(m K). This value is slightly higher than Yb:GGG (8 W/(m K) undoped, 7.5 W/(m K) with 5.7% doping) [‎22], similar to Yb:YAG (about 8 W/(m K) with 2% doping) [‎23] and slightly lower than undoped LuAG (reported between 8.3 and 9.6 W/(m K)) [‎24]. The overall error on the thermal conductivity results from the statistical error (which did not exceed 2%) and from the systematic error (estimated to be 6%, due to the inaccuracy in the measurement of the distance between the thermometers providing the temperature gradients). It must be also noticed that this value is consistent with the value (7.8 W/(m K)) measured by Kuwano et al. [‎17] for 1% Nd doped Gd3(Al0.4,Ga0.6)5O12, i.e. with a host composition close to the one analyzed here.

3. Laser emission measurements

The sample was shaped as a parallelepiped with 4 × 4 × 10 mm3 sides. It was inserted with one of the 4 mm sides parallel to the axis of the end-pumped laser cavity shown in Fig. 5. Mirrors EM and FM are dichroic (high transmission for the pump wavelength, high reflection for the laser wavelength), set at a distance of 55 mm. The distance between FM and the output coupler OC is 165 mm. The sample is soldered with Indium by its end face on a copper heat sink cooled by water at 18°C, and placed near to the EM. As the sample has no AR coating, to reduce the Fresnel losses it was oriented to re-inject the face reflections on the cavity axis. The pump source is a fiber coupled laser diode (wavelength 938 nm, 200 μm fibre core diameter, 0.22 fibre NA). The fiber tip is reimaged on the sample by two achromatic doublets (nominal magnification 1). The pump intensity distribution in the focal plane is almost Gaussian (radius ∼150 μm @ 1/e2). The maximum incident power was 22 W CW. The pump absorption was measured during the laser action at each incident power, by measuring the residual power transmitted by the sample, refocused by a collecting lens (L) on the auxiliary power meter M. Tunable emission was obtained by placing a Brewster ZnSe prism (apex angle 41.8°) and a slit placed between FM and OC. The wavelength was measured with a 60 cm focal length spectrometer equipped with a multichannel detector (resolution 0.4 nm).

The results in terms of laser output power, slope efficiency, optical-to-optical efficiency and radiation wavelengths are summarized in Table 1. The sample absorbed about 44% of the incident pump power (up to 9 W).

Lasing occurred on a single peak (typical linewidth 1.4 nm FWHM). The wavelength shifted from 1030 nm to 1026 nm for increasing T. With T = 2.2% emission occurred at 1043.9 nm for output power below 0.72 W; above this level the laser emitted simultaneously at 1043.9 and 1030 nm.

The tuning range was investigated by the tunable cavity described above, using the OC with T = 2.2%. In these measurements, the crystal was pumped in quasi-CW regime (20 ms duration, frequency 10 Hz). The peak output power as a function of the emission wavelength is shown in Fig. 6(b). The maximum output power (300 mW) is obtained at 1026 nm while the tuning curve extends from about 996 nm to 1050 nm.

4. Discussion

The assessment of the crystal structure by means of X-ray diffraction (Fig. 2) resulted in a crystal lattice constant a = 12.231 Å. This value is very close to the average value (12.2435 Å) between the lattice constant of Gd3Ga5O12 (GGG, JCPDS Card No. 13-0493, a = 12.376 Å) and Gd3Ga5O12 (GAG, JCPDS Card No. 32-0383, a = 12.111 Å), see Fig. 3. This implies that the actual composition of our sample is very close to the nominal one, i.e. Gd3(Al0.5Ga0.5)5O12.

Concerning the zero-phonon line (Fig. 3) we notice that in the low temperature spectrum it appears as a single peak at 969.6 nm. This indicates that the Yb ions are located on a single crystallographic site: multiple sites, originated for instance by lattice defects, would result in a splitting of the zero-phonon line. The disordered crystal structure results in an inhomogeneous broadening of the zero phonon line of 1.27 nm. At room temperature, due to the mixed composition the zero-phonon line shifts from 971 nm (observed in GGG [‎25]) to 970.3 nm in our GAGG while the peak absorption increases from 0.7 × 10−20 cm2 in GGG to 1.18 × 10−20 cm2 in our sample. An increase from 0.45 to 0.91 ( × 10−20 cm2) of the peak absorption, which is located near 943 nm, is observed as well. For the GAGG composition with Al/Ga = 0.1/0.9 [‎14] the absorption cross section was more similar to GGG (0.56 × 10−20 cm2 @ 942 nm and 0.43 × 10−20 cm2 on the zero line). The emission spectrum is peaked at 1027 nm, shifted by 2 nm from the peak position in Yb:GGG (at 1025 nm). The peak emission cross section is similar to other garnets (1.83 × 10−20 cm2 vs. 2.0 × 10−20 cm2 in GGG, 2.3 × 10−20cm2 in YAG, 2.5 × 10−20cm2 in LuAG [‎24]), but the peak is broader (12.1 nm FWHM) than in GGG, YAG and LuAG (8 nm, 9 nm and 7.3 nm respectively). It must be noticed that the emission bandwidth of the Yb:GAGG with Al/Ga = 0.1/0.9 reported in [‎14] is slightly broader (13.8 nm) than in our composition.

The lifetime of the 2F5/2 level (0.91 ms) was longer than in GGG (0.83 ms [‎26]) and similar to Yb:YAG (0.95 ms [‎19]) and LuAG (0.965 msec [‎24]). For the lifetime we obtained this same value from two independent methods (that is, on powdered samples and by means of the pinhole method, as described above), both aimed to minimize reabsorption effects. This result should then have a high degree of reliability.

It must be noticed that Zhang et al. [‎14] reported a higher value (1.38 ms) of the 2F5/2 level lifetime. This value is much longer than our findings; due to their low Al/Ga ratio (0.1/0.9), a value more similar to Yb:GGG (0.83 ms, see [‎26]) could be expected. On the other hand, the measurement reported in that paper is simply defined as “fluorescence decay measurement”, and no remedies are reported to avoid reabsorption effects. Therefore, this result may be affected by radiation trapping effects. As this value is needed for the evaluation of the emission cross section spectrum (with the Fuchtbauer-Ladenburg formula), this could also lead to an underestimation of the emission cross section (with a peak value, 1.1 × 10−20cm2, which is indeed much lower than in Yb:GGG). For these reasons in our opinion the spectroscopic data reported in [‎14] should be treated with caution.

No comparison with Yb:GAG is currently possible, because to the best to our knowledge no spectroscopic studies on Yb:GAG crystals are available in literature, nor even results regarding the laser emission.

Regarding the laser emission, the sample has shown a maximum output power of 4.0 W CW with high slope and optical efficiencies (respectively 60% and 46% in the most favorable conditions), i.e. higher than those reported so far for Yb:GAGG with Al/Ga = 0.1/0.9 (respectively 53.2% and 41.6% [‎14]), even though with a lower maximum output power.

Recently, Zhao et al. [‎16] reported the high repetition rate pulsed operation of a 6% doped Yb:GAGG with Al/Ga = 0.1/0.9, obtained with an actively Q-switched cavity, with a maximum average output power of 1.4W and a maximum slope efficiency of 32%. These values are quite lower than our results, but it must be taken into account that usually the Q-switch devices introduce additional intracavity losses which reduces the energy extraction efficiency with respect to the simple CW operation. The spectroscopic data reported there are recalled from [‎14].

Our slope efficiency is also higher than that previously reported for Yb:GGG (46% [‎22]). In our case the output power was limited only by the available pump power, but we did not observe signs of output degradation due to thermal effects.

The tuning range was quite broad, from 996 nm to 1050 nm (54 nm). The peak power occurs at 1026 nm, slightly shorter than the peak of the emission cross section spectrum (1027 nm) and similar to the free running lasing wavelength obtained with high output losses. To our knowledge this is the first assessment of the tuning range for Yb:GAGG of any composition. A comparison with previous results is possible only with Yb:GGG: the tuning curve reported in [‎22] was peaked at 1038 nm and extended from 1022 nm to 1075 nm, i.e. with a similar width, but shifted to longer wavelengths.

To support this result we calculated the theoretical tuning range achievable with our experimental set-up in conjunction with the emission bandwidth of our sample. For this purpose, we used a previously reported model [‎27] based on rate equations. The small signal gain is calculated as a function of the wavelength, using the absorption and the emission cross section spectra of the sample and the parameters of the experimental set up (pump beam size and power, cavity mode size, cavity roundtrip losses). The tuning range is the wavelength interval where the small signal gain matches or exceeds the cavity losses over a roundtrip. In our experiment, the roundtrip losses of the tunable cavity were evaluated at about 18% (due to the relatively high Fresnel losses introduced by the ZnSe prism). The calculated tuning range extended from 1003 nm to 1053 nm. This result is fairly in agreement with the experimental results. It must be noticed anyway that this kind of calculations is very sensitive to the uncertainties in the determination of the emission cross section spectrum, in particular on the twings of the emission peak, and it cannot replace an experimental evaluation.

5. Conclusions

We have presented the spectroscopic investigation and laser emission demonstration of Yb:GAGG with 0.5/0.5 Al/Ga balance. To our knowledge, this is the first characterization of the spectroscopic and laser properties of Yb:GAGG with such a high Al/Ga ratio. This crystal has demonstrated to be an interesting laser material for high power laser applications, with good potentialities for the generation and the amplification of ultrashort laser pulses.

The main effect of the mixed composition on the Yb spectroscopy is a significant broadening (about 50% FWHM) and a slight shift (about 2 nm) of the emission spectrum with respect to the parent composition Yb:GGG. This broad bandwidth should allow the generation and amplification of ultrashort laser pulses in the sub-100 fs time scale. The upper laser level lifetime is longer than in Yb:GGG, which is beneficial in terms of energy storage capabilities. The thermal conductivity at room temperature is quite high, similar to YAG and LuAG with similar doping levels, which is favorable for the development of high power laser systems. Such a high thermal conductivity was already reported in literature (see for instance [‎17]), nonetheless it is quite unusual in the scenario of the disordered crystals.

In terms of laser performance, the material has shown a quite high slope efficiency (up to 60%), slightly higher than that reported so far for Yb:GGG [‎22] and for Yb:GAGG with ratio Al/Ga = 0.1/0.9 [‎14]. We point out that in our experiment the pumping conditions were under-optimized, due to the low doping of the sample (resulting in a relatively low pump absorption) which in turn required a long sample length (4 mm), resulting in relatively poor matching between the highly divergent pump beam and the laser mode.

The tuning range was blue-shifted with respect of Yb:GGG and only slightly broader, despite that the emission spectrum is substantially broader than in Yb:GGG. This is probably due again to the relatively low pump absorption of the sample that prevents laser oscillation above 1055 nm, where laser threshold increases due to the decreasing emission cross section. Improvements are expected in terms of slope efficiency and tuning range by using samples with a higher doping and a smaller thickness.
