Abstract: | We report an efficient laser emission on the 1064 nm 4 F 3/2 to 4 I 11/2 transition in mixed vanadate crystal Nd:Y0.36Gd0.64VO4 under the pump with diode laser at 880 nm. Continuous wave (CW) 10.7 W output power at 1064 nm is obtained under 17.8 W of incident pump power; the slope efficiency with respect to the incident pump power was 71.2%. Moreover, intracavity frequency doubling with LiB3O5 (LBO) nonlinear crystal yielded 4.6 W of green light at 532 nm. An optical-to-optical efficiency with respect to the incident pump power was 25.8%. |
