Abstract

A 785 nm diode-side-pumped high-power high-pulse-repetition-frequency Q-switched 2μm Tm:YAG laser system is reported. Under a pump power of 1300 W, a 171.4 W average output power is achieved at a pulse repetition frequency of 10 kHz. To our knowledge, this is the highest average output power for a diode-pumped all solid-state Q-switched 2 μm Tm:YAG laser. The laser output corresponds to an optical-to-optical conversion efficiency of 13.3% and a slope efficiency of 18.9%.
