摘要
采用940 nm InGaAs激光二极管(LD)阵列端面抽运片状Yb:YAG晶体,谐振腔采用V形有源镜构型,实现了1030 nm红外激光输出。实验中分别测试了激光器在不同重复频率(1 Hz,2 Hz,5 Hz,10 Hz)条件下的激光输出特性。当输出耦合镜的反射率为73%,在抽运能量为7.6 J(功率密度为13 kW/cm3)时,1 Hz重复频率输出稳定运行于2.43 J,光-光转换效率为32%,斜率效率为54.5%;10 Hz重复频率输出稳定运行于1.76 J,光-光转换效率为23.2%,斜率效率为43.3%。

The infrared laser output at 1030 nm is obtained. The output performance of the laser under different repeat frequencies （1 Hz, 2 Hz, 5 Hz, 10 Hz） is experimentally tested. With output mirror reflectivity of 73% and pump energy of 7.6 J （power of 13 kW/cm^2）, the output energy of 2.43 J is obtained with repeat frequency of 1 Hz, the optical-optical efficiency is 32% and the slope efficiency is 54.5 %; the output energy of 1.76 J is obtained with repeat frequency of 10 Hz, the optical-optical efficiency is 23.2% and the slope efficiency is 43.3%.
