摘要

High-efficient continuous wave (cw) and actively Q-switched Tm:YAG ceramic lasers were described successfully. Pumping with fiber coupled laser diode at 792 nm, the maximum cw output power of 5.21 W with improved beam quality was obtained with a slope efficiency of 46.1%. The shortest pulse width of 107 ns was achieved with the pulse repetition frequency (PRF) of 0.5 kHz, resulting in a largest pulse energy of 1.44 mJ and a highest peak power of 13.42 kW.
