We report here a diode pumped Nd∶YVO4 laser emitting at 1342 and 671nm.A maximum output power of 1.75W at 1342nm was obtained under an incident pump power of 5.45W,with an optical-to-optical conversion efficiency of up to 32.1%.With a type Ⅰ noncritically phase-matched LBO crystal as the intracavity frequency doubler,over 500mW of 671nm light was obtained at 6W of incident pump power,the optical-optical conversion efficiency being 8.3%.The output power fluctuates less than 5% while the temperature change of the LBO crystal oven was maintained ±0.5℃ at the phase-matched temperature.
