摘要
理论设计和制作了Yb∶YAG陶瓷板条,通过铟砷化镓(InGaAs)二极管抽运、1030 nm种子激光注入以及双程放大,在室温下实现了高功率的1030 nm激光输出。种子激光注入功率为1.18 kW和总抽运功率为19.98 kW时,获得了5.97 kW的放大激光功率,光-光转换效率约为24.0%,斜率效率为27.9%。测量了Yb∶YAG陶瓷板条的透射波前,模拟了不同耦合效率和温度时的输出功率。实验结果表明,室温下Yb∶YAG在高亮度抽运和高亮度种子光注入时可以实现高功率的激光输出。
Abstract
A Yb∶YAG ceramic slab is designed theoretically and fabricated, and the high power laser output is achieved at 1030 nm under room-temperature with InGaAs diode pumping, 1030 nm seed laser injecting and double-pass amplifying. The amplified laser power is 5.97 kW when the total pumping power is 19.98 kW and the injected power of the seed laser is 1.18 kW. The optical-to-optical conversion efficiency is 24.0% and the slope efficiency is 27.9%. The transmission wavefront of the Yb∶YAG ceramic slab is measured and the output powers with different coupling efficiencies and working temperatures are simulated. The experimental results show that the high power laser output can be achieved in Yb∶YAG under room-temperature with high intensity pumping and high intensity seed laser injecting.
