title: High-efficiency Nd:LuVO4 quasi-three-level 916 nm laser under polarized pumping.
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.
