Abstract

This paper demonstrates a plano-concave microchip vertical-external cavity emitting laser (mu-VECSEL) operating at 1.05 mum. The cavity is composed of a semiconductor structure, comprising an active region grown on top of a distributed Bragg reflector (DBR), and a diamond heatspreader with its outer surface shaped as a spherical microlens. This stable optical cavity has a signal spot diameter of ~19.8 mum on the active region and of ~21 mum at the concave micro-mirror facet.
