An efficient compact diode-pumped Yb:YAl3(BO3)4 laser operating at room temperature is demonstrated. Output powers of 14.0 and 8.5 W are generated in continuous-wave and passively Q-switched operation, respectively. Laser pulses of 262.8 μJ in energy and 8.1 ns in duration are obtained, the corresponding peak power amounting to 32.4 kW.
Continuous-wave (CW) and passively Q-switching laser performance of the Yb:CNGG and Yb:CLNGG disordered garnet crystals are compared. CW output powers of 6.3 and 7.5 W are generated from the Yb:CNGG and Yb:CLNGG lasers, with slope efficiencies measured to be 63 and 74 %, respectively. In passively Q-switched operation, the average output power reaches 2.0 and 3.1 W, with slope efficiencies of 56 and...
