在重复频率为10 kHz、光-光转换效率为15.2%的二极管侧面抽运调Q Nd：YAG棒激光器上，利用腔内倍频技术，在平均输出功率为120 W时，获得了M2 = 6.2的绿光光束质量。为了在高平均功率下获得高光束质量，激光器采用了热近不稳定腔设计，在L形平-平腔中采用双棒双折射补偿。绿色激光器在4 h内输出功率波动小于0.9%。
We have obtained green-beam quality of M2 = 6.2 at an average output power of 120 W by intracavity frequency doubling of a diode-side-pumped, Q-switched Nd:YAG rod laser with a repetition rate of 10 kHz and an optical-to-optical conversion efficiency of 15.2%. To achieve high-beam quality at high average power, the laser employs a thermally near-unstable resonator design with two-rod birefringence compensation in an L-shaped flat-flat cavity. The output power fluctuation of the green laser remains less than 0.9% in 4 h.
