报道了由15 W连续激光二极管端面抽运的Nd:YAG激光器, 自由运转时输出功率达到4.5 W, 斜效率达到44%, 声光调Q的重复率由3～65 kHz可变。 10 kHz时, 峰值功率达到28 kW, 脉宽8 ns。 还分析了激光二极管抽运的声光调Q高重复率激光器设计中的几个重要因素。 从理论上分析了不同频率时激光单脉冲能量、 斜效率产生区别的主要原因。

A 15 W CW diode laser end-pumped Nd:YAG laser is reported. The output power of 4.5 W and the slope efficiency of 44% are obtained in free runing cavity. By using Q-switch the peak power of 28 kW and pulse width of 8 ns are obtained at repetition rate of 10 kHz. The repetition rate varied from 3 kHZ to 65 kHZ. Several important factors in cavity design are analyzed. The dependences of pulse energy and slope efficiency on the repetition rates are analyzed. The theory conclusions fit well with the experimental results.
