We demonstrated an 879-nm-diode-pumped Nd:GdYTaO laser in continuous-wave-(CW), pulse-pumped, pulse-reflection-mode Q-switched, and cavity-dumped burst-mode Q-switched operations for the first time. A maximum output power of 9.3 W at 1,066 nm was obtained in the CW operation with a slope efficiency of ~48%. The slope efficiency reached the value of ~68% in the pulse-pumped operation. A peak power of 150 kW and pulse width of 3.4 ns were obtained in the cavity-dumped burst-mode Q-switched operation at a Q-switching repetition rate of 20 kHz.
我们首次展示了一款879纳米二极管泵浦的Nd:GdYTaO激光器，它可实现连续波（CW）、脉冲泵浦、脉冲反射模式调Q以及腔倒空突发模式调Q运转。在连续波运转中，于1066纳米处获得了9.3瓦的最大输出功率，斜率效率约为48%。在脉冲泵浦运转中，斜率效率达到了约68%的值。在腔倒空突发模式调Q运转中，当调Q重复频率为20千赫兹时，获得了150千瓦的峰值功率和3.4纳秒的脉冲宽度。
