✦ Synopsis

CW laser output has been demonstrated for polycrystalline transparent 10 at.% Yb 3+ -doped Y 2 O 3 ceramics. Endpumped with 970 nm laser diode, a maximum output power of 5.5 W has been obtained with absorbed pump power of 31.1 W. The slope efficiency is 25% while the threshold pump power is 5.6 W. Saturation is not observed in our experiments, indicating higher laser output can be expected with higher pump power.

We report on a high-energy ceramic Nd^3+^:Y~3~Al~5~O~12~ laser. Under the pyrotechnic explosion pumping, quasi-CW output power of about 1.1 KW (≈5.5 J) at 1.06415 μm wavelength (^4^F~3/2~ → ^4^I~11/2~ lasing channel) was achieved. Pyrotechnically pumped crystalline lasers are characterized by low si

We report for the first time (to our knowledge) a diode-pumped Nd:SGG laser emitting at 1070 nm. A power of 1.23 W at 1070 nm has been achieved in continuouswave (CW) operation with a fiber-coupled laser diode emitting 18.2 W at 806 nm. Intracavity second-harmonic generation (SHG) in CW mode has als
