摘要
研究了高功率Yb:YAG薄片激光器连续及腔倒空调Q输出性能。基于平面波理论,建立Yb:YAG准三能级激光连续运转模型,对薄片激光器的晶体掺杂和抽运结构进行优化。通过优化实验方案,研究半导体激光器抽运Yb:YAG薄片激光器连续输出性能,在抽运功率为199 W时,获得功率为100 W的1030nm激光输出,光-光转换效率为50.2%,斜率效率为56.8%。利用RTP电光调Q开光,搭建Yb:YAG电光腔倒空激光器,研究1030nm脉冲输出性能,获得了脉冲宽度为20.2ns的高重复频率1030nm脉冲激光,脉冲重复频率为10~100kHz,当重复频率为10kHz时,1030nm激光的最大峰值功率达到109.8kW。
Research on high power continuous wave and cavity dumped Yb： YAG thin disk lasers is conducted. Based on the plane-wave quasi-three-level laser model, the parameters of Yb： YAG thin disk laser are optimized. The maximum output power in laser diode pumped Yb： YAG thin disk laser at 1030 nm reaches 100 W with an optical-to-optical efficiency of 50.2% and a slope efficiency of 56.8%. By using RTP electro-optical Q switched, the cavity-dumped Yb： YAG thin disk laser at 1030 nm is constructed. A constant pulse duration of 20.2 ns is achieved within the repetition rate from 10 kHz to 100 kHz. The maximum output peak power at 1030 nm achieves 109.8 kW with a repetition rate of 10 kHz.
