摘要
报道了通过键合Yb∶YAG激光陶瓷来强化Cr,Yb∶YAG自调Q微片激光器激光性能的研究结果。实现了Yb∶YAG/Cr,Yb∶YAG自调Q微片激光器的激光输出。当吸收抽运功率为7.1 W时获得了0.53 W的自调Q激光输出,对应的光光转换效率为7.5%。在实验中获得了脉冲能量大于25 μJ、脉冲宽度小于3 ns、峰值功率高达9 kW的自调Q激光脉冲输出。同时研究了输出耦合镜透射率对Yb∶YAG/Cr,Yb∶YAG自调Q微片激光器激光性能的影响。
Abstract
Enhancement of Cr,Yb∶YAG self-Q-switched microchip laser by bonding Yb∶YAG ceramic is investigated. Yb∶YAG/Cr,Yb∶YAG self-Q-switched microchip lasers is demonstrated. Average output power of 0.53 W is obtained under absorbed pump power of 7.1 W. Laser pulses with pulse energy over 25 μJ, pulse width shorter than 3 ns and peak power over 9 kW are achieved. The effect of transmission of output coupler on the laser performance is also addressed.
