Abstract :
A report is presented on intracavity frequency doubling of electrically pumped vertical-extended cavity surface-emitting lasers (VECSELs), establishing a blue light source emitting near 485 nm wavelength. The VECSELs have an InGaAs/GaAs gain region and incorporate a nonlinear optical crystal for frequency doubling. Continuous-wave optical output powers of more than 1.5 mW are achieved.
