Abstract

We present a diode-pumped broadband tunable single-frequency and frequency-doubling $\mathrm{Nd}\text{:}{\mathrm{YVO}}_4/\mathrm{LBO}$ laser with high output power of 10.5 W in all tuning ranges around 532 nm. An etalon placed inside the resonator and the laser gain medium in a wedge shape are used for the coarse- and fine-tuning elements, respectively. By independently scanning the temperatures of the two tuning elements, broadband tunable ranges of 12 and 24 GHz have been achieved, respectively, for the fundamental and the second-harmonic waves.
