Abstract

We report herein the enhancement of output power and optical efficiency of a quasi-three-level Nd:YVO₄ laser through a double-end polarized pumping scheme, which improves the usually insufficient pump absorption of the short laser gain medium with low doping concentration, and meanwhile alleviates the influence of thermal effect. 17.7 W laser output at 914 nm is obtained under the launched 808-nm pump of 53.0 W, corresponding to an optical efficiency of 33.4%.

摘要

我们在此报告通过双端偏振泵浦方案提高了准三能级Nd:YVO₄激光器的输出功率和光学效率，该方案改善了通常低掺杂浓度短激光增益介质泵浦吸收不足的问题，同时减轻了热效应的影响。在53.0 W的808 nm泵浦光注入下，获得了914 nm处17.7 W的激光输出，光学效率为33.4%。
