Abstract:
600 mW second-harmonic blue light at 488 nm has been generated by use of a master-oscillator power amplifier diode laser system as a pump source with a maximum optical output power of 4 W in continuouswave operation. For frequency doubling, a periodically poled MgO:LiNbO₃ bulk crystal was used in a singlepass configuration. A conversion efficiency of 15% and an overall wall-plug efficiency of 4% were achieved.
