部分端面抽运的混合腔板条激光器是一种新型的全固态激光器,采用这种结构,实现了高重复率调Q运转。在脉冲抽运情况下,1kHz运转时,得到脉宽4.6ns,单脉冲能量4.5mJ的激光输出。在连续抽运调Q输出情况下,5kHz高重复率运转时,获得了脉宽6ns,单脉冲能量3.1mJ的脉冲序列输出,平均功率超过15W;当重复率高达25kHz时,得到脉宽9.5ns,单脉冲能量1.2mJ的激光输出,平均功率达30W。实验结果表明,输出水平还有很大的提升空间。 Partially-end-pumped hybrid cavity slab lasers are a new type of all-solid-state laser that uses this structure to achieve high repetition rate Q-switching. In the case of pulse pumping, 1kHz operation, get pulse width 4.6ns, single-pulse energy 4.5mJ laser output. The pulse sequence output of 6ns pulse width and 3.1mJ pulse energy was obtained with continuous pumping Q-switched output at 5kHz high repetition rate. The average power exceeded 15W. When the repetition rate was up to 25kHz, the pulse width was 9.5ns , Single pulse energy of 1.2mJ laser output, the average power of 30W. Experimental results show that the output level there is still much room for improvement.
