Abstract

Intracavity frequency doubling of an optically pumped GaInNAs semiconductor disk laser by a periodically poled near-stoichiometric lithium tantalate crystal has been investigated. Stable second-harmonic generation at 610 nm has been achieved with an output power of 730 mW, limited only by the spectral acceptance range and Fresnel losses of the crystal. Spectral tuning of 8 nm was realised with a Fabry-Pérot etalon.
