Abstract

An optically pumped red vertical-external-cavity surface-emitting laser with an AlInGaP gain region produced more than 1 W of continuous-wave output power at a wavelength of 675 nm. Frequency doubling in a beta-barium borate crystal placed at an intracavity beam waist generated 120 mW of total output power at 338 nm. Using an intracavity birefringent filter a second harmonic tuning range of ~5 nm was achieved.
