Abstract
Holmium ions (Ho3+) are interesting because of their emission in the eye-safe spectral range slightly above 2 µm due to the 5І7 → 5І8 transition. Tm3+,Ho3+-codoping is frequently used for excitation of Ho3+ ions: Tm3+ ions (donors) efficiently absorb pump radiation at ~0.8 µm and non-radiatively transfer their energy to Ho3+ ions (acceptors), 3F4 (Tm3+) → 5I7 (Ho3+). The codoping scheme also benefits from the combined gain bandwidths of both active ions which is attractive for broadband wavelength tuning and ultrashort pulse generation [1]. Cubic sesquioxides A2O3 (where A = Y, Lu, Sc or their mixture) are the well-known host matrices for rare-earth doping. They can be elaborated in the form of transparent polycrystalline ceramics [2]. In the present work, we report on the first Tm,Ho:A2O3 ceramic laser.
