中文摘要开展了激光二极管(LD)抽运的全固态热容激光器的理论与实验研究, 数值模拟了在热容工作条件下侧面抽运的Nd:YAG板条激光器的热透镜效应, 分析了热透镜效应对激光输出的影响, 并进行了相应的实验论证。实验中采用的晶体尺寸为57 mm×40 mm×4 mm, 激光二极管阵列的抽运峰值功率为12 kW, 重复频率为1 kHz, 占空比为20%, 为了获得较高的增益, 将抽运光通过光学系统进行聚焦, 抽运光在晶体侧面的光斑大小为15 mm×57 mm。实验中观察了1 s内的脉冲能量输出的波动情况, 在开始工作的; Experimental and theoretical studies of a laser diode (LD) array pumped solid-state heat capacity laser (SSHCL) were reported. The thermal lens effect of heat capacity slab Nd:YAG laser under side pumped condition was calculated, and the influence of the thermal lens effect on the output energy fluctuation of the SSHCL was studied. In experiment, slab crystal size is 57 mm×40 mm×4 mm, peak pumped power of the LD array is 12 kW with 1 kHz repetitive frequency and 20% duty ratio. In order to obtain high laser gain, the pump beams were focused as small as 15 mm×57 mm spot in profile. In the experimental examination, the output of single pulse energy was 1 J at the beginning, after 1 s operation it fell down to 50%.
