Abstract

A frequency-tunable Q-switched laser operation at 1064 nm pumped by a wavelength-locked 878 nm semiconductor diode was reported. Under CW operation mode, the maximum output power of 30.5 W was obtained while the pumping power was 55.9 W, and the light-light conversion efficiency was 54.56 %; While in the Q-switching operation mode, the maximum output power of 24.93 W was obtained when the pumping power was 53.05 W, and the light-light conversion efficiency was 46.54 %. Provides stable operation in Q-switching mode between 60 kHz and 300 kHz repetition frequency with a pulse width range of 22.5 ns to 24 ns. The laser with beam quality M ² _x=1.21 and M² _y=1.33 was obtained.
