Abstract

An efficient laser-diode-pumped Nd:LuVO4 916 nm laser by using the polarized pumping is reported. The maximum continuous-wave output power of 4.75 W is achieved at the incident pump power of 27.8 W, with an optical-to-optical efficiency of ~17.1% and a slope efficiency of ~29.5%. The slope efficiency is up to 45.4% with respect to the absorbed pump power and nearly 1.7 times higher than the previous results ever reported under the 808 nm diode laser pumping. The beam quality is measured to be M2 ~ 2.3 at the output power of 4.75 W.

摘要

报道了一种采用偏振泵浦的高效激光二极管泵浦Nd:LuVO4 916 nm激光器。在27.8 W的入射泵浦功率下，实现了4.75 W的最大连续波输出功率，光光效率约为17.1%，斜率效率约为29.5%。相对于吸收的泵浦功率，斜率效率高达45.4%，比此前报道的808 nm二极管激光泵浦下的结果高出近1.7倍。在4.75 W的输出功率下，测量得到的光束质量为M2~2.3。
