Abstract

We report a continuous wave operation of a quantum-well and multi-pass-pumped AlGaInP based red vertical-external cavity surface-emitting laser emitting at 660 nm. The laser output power was 1.5 W with a slope efficiency of 35 %. The critical role of optimizing the sample design both for the pump and laser wavelengths, pump spot size, and the number of pump light passes were experimentally investigated.
