By use of CW diode laser stacked arrays, side-pumping Q-switched composite ceramic Nd:YAG rod laser based on a type II KTP crystal intracavity frequency-doubled, a high power high stability green laser has been demonstrated. Average output power of 104 W is obtained at a repetition rate of 10.6 kHz with a diode-to-green optical conversion efficiency of 10.9%. For the average output power of about 100 W, the measured pulse width is 132 ns with power fluctuation of less than 0.2%. The experimental results show that the green laser system using this novel ceramic Nd:YAG offers better laser performance and output stability than the traditional single Nd:YAG crystal green laser system with the same operating conditions and experimental configuration.
通过使用连续波二极管激光堆叠阵列，侧面泵浦基于II型KTP晶体腔内倍频的调Q复合陶瓷Nd:YAG棒激光器，已实现了高功率高稳定性绿色激光器。在重复频率为10.6kHz时获得了104W的平均输出功率，二极管到绿色光的转换效率为10.9%。对于约100W的平均输出功率，测得的脉冲宽度为132ns，功率波动小于0.2%。实验结果表明，在相同工作条件和实验配置下，使用这种新型陶瓷Nd:YAG的绿色激光系统比传统的单Nd:YAG晶体绿色激光系统具有更好的激光性能和输出稳定性。
