Abstract We report a high-power high-efficient continuous-wave (cw) diode-end-pumped Nd:YVO4 1342-nm laser with a short plane-parallel cavity and an efficient cw intracavity frequency-doubled red laser at 671nm with a compact three-element cavity. At incident pump power of 20.6W, a maximum output power of 7W at 1342nm is obtained with a slope efficiency of 37.3%. By inserting a type-I critical phase-matched LBO crystal as intracavity frequency-doubler, a cw red output as much as 2.85-W is achieved with an incident pump power of 16.9W, inducing an optical-to-optical conversion efficiency of 16.9%. To the best of our knowledge, this is the highest output of diode-pumped solid-state Nd:YVO4 red laser. During half an hour, the red output is very stable, and the instability of output power is less than 1%.
