摘要：

A diode-pumped passively Q-switched 1065 nm laser with a novel Nd:Gd0.89La0.1NbO4 mixed crystal was demonstrated for the first time to the best of our knowledge. First, the crystal characteristics were investigated. In the continuous-wave (CW) operation, when the absorbed pump power was 12.24 W, the maximum CW output power of 3.06 W was obtained with the optimum transmission (20%) of the output plane coupler. In the passively Q-switched situation, when Cr4+:YAG crystal with an initial transmission of 90% served as the Q-switched saturable absorber, the maximum repetition rate, pulse peak power and minimum pulse width were 24.5 kHz, 1.13 kW and 32 ns, respectively, at the absorbed pump power of 12.24 W.
