Abstract

We report an efficient laser emission on the 1341 nm 4F3/2 to 4I13/2 transition in Nd:GdVO4 under the pump with diode lasers at 888 nm. Continuous wave (CW) 6.58 W output power at 1341 nm is obtained under 18.3 W of incident pump power; the slope efficiency with respect to the incident pump power was 45.1%. Moreover, intracavity frequency doubling with LiB3O5 (LBO) nonlinear crystal yielded 1.77 W of red light at 670.5 nm.
