Abstract

We present a pumping scheme for a quasi-three-level solid-state laser. The scheme uses a slab laser configuration with the pump light incident from the slab corners. A diode-corner-pumped composite Yb:YAG-YAG slab laser operating in high-power cw mode was designed to prove the scheme. As much as 520 W of output power was obtained from a single 1-mm-thick composite slab with 0.5-at. %-doped Yb:YAG. The slope efficiency and the optical-to-optical efficiency with respect to the pump power were 32% and 25%, respectively. This result shows the validity of the corner-pumping concept and its feasibility in the development of high-power solid-state lasers.

摘要

我们提出了一种用于准三能级固态激光器的抽运方案。该方案采用板条激光器结构，泵浦光从板条的角部入射。设计了一种角部二极管抽运的复合Yb:YAG - YAG板条激光器，以验证该方案，其工作在高功率连续波模式。从一块厚度为1毫米、Yb:YAG掺杂浓度为0.5原子百分比的复合板条中获得了高达520瓦的输出功率。相对于泵浦功率的斜率效率和光光效率分别为32%和25%。这一结果表明了角抽运概念的有效性及其在高功率固态激光器开发中的可行性。
