Abstract

We report, on the development and the demonstration of a tunable, watt-level, blue-green, linearly polarized vertical-external-cavity surface-emitting lasers operating around 488 nm by intracavity second-harmonic generation. By using lithium triborate crystal, we have achieved over 1.3 W continuous wave blue-green power at 488 nm with a 5 nm tunability.
