Paper Abstract

Compared with one-pass pumped system, diode laser two-pass pumped Tm:YAG lasers in an active mirror configuration will result in a 24% decrease in threshold and 16% increase in slope efficiency. Using a 3-W diode-laser as the pump source, we demonstrated CW and AO Q-switched Tm:YAG lasers in an active mirror configuration. The maximum output power in CW operation exceeded 765 mW and the corresponding slope efficiency reached 45%. In the AO Q-switched operation, we obtained 1.2 mJ output energy with a pulse width of 370 ns when the repetition rate was 120 Hz.
