All-solid-state CW Nd:LuVO4-LBO laser at 533 nm under direct 888 nm pumping

Abstract

We report an efficient laser emission on the 1066 nm 4 F 3/2 to 4 I 11/2 transition in Nd:LuVO4 under the pump with diode laser at 888 nm. Continuous wave (CW) 11.2 W output power at 1066 nm is obtained under 18.3 W of incident pump power; the slope efficiency with respect to the incident pump power was 71.9%. Moreover, intracavity frequency doubling with LiB3O5 (LBO) nonlinear crystal yielded 4.2 W of green light at 533 nm. An optical-to-optical efficiency with respect to the incident pump power was 23.0%.
