Abstract

Abstract: A diode-pumped passively Q-switched 1066 nm laser with a novel Nd:Gd0.69 Y0.3 NbO4 mixed crystal was demonstrated for the first time to the best of our knowledge. In the continuous-wave (CW) operation, optimization selection of output couplers was carried out, and a maximum output power of 2.13 W was obtained when the plane mirror with transmission of 25% was chosen and the absorbed pump power was 10.5 W. The Cr 4+ :YAG passively Q-switched Nd:Gd0.69 Y0.3 NbO4 laser performance was investigated. At an absorbed pump power of 10.5 W, using Cr 4+ :YAG with initial transmission of 80%, the obtained minimum pulse width was 7.2 ns with the pulse repetition rate of 19 kHz. The single pulse energy and peak power were estimated to be 26.7 µ J and 3.7 kW, respectively.
