Abstract

We demonstrate a linearly polarized Tm:YAP slab laser pumped by fiber-coupled laser diodes. The maximum output power is 202 W at 1937.5 nm with a slope efficiency of 47.4% and an optical-to-optical efficiency of 35.6%. The beam quality factors are 10.1 and 8.33 in and directions, respectively. Using the Tm:YAP laser as the pump source, the maximum power of the Ho:YLF oscillator is 113 W at 2063.3 nm, corresponding to an optical-to-optical efficiency of 55.9%. In addition, the beam quality factors of the Ho:YLF laser are ∼1.5 at maximum power.

摘要

我们展示了一种由光纤耦合激光二极管泵浦的线性偏振Tm:YAP板条激光器。在1937.5nm处的最大输出功率为202W，斜率效率为47.4%，光光效率为35.6%。光束质量因子在x和y方向分别为10.1和8.33。以Tm:YAP激光器作为泵浦源，Ho:YLF振荡器在2063.3nm处的最大功率为113W，对应的光光效率为55.9%。此外，Ho:YLF激光器在最大功率时的光束质量因子约为1.5。
