Spectral Narrowing and Locking of a Vertical-External-Cavity Surface-Emitting Laser Using an Intracavity Volume Bragg Grating

摘要

We report the use of a volume Bragg grating as an output coupler mirror to improve and stabilize the spectral characteristics of 1058-nm vertical-external-cavity surface-emitting laser which is thermally managed using an intracavity diamond heatspreader. Spectrally narrow and locked emission with up to 645 mW of TEM_(0,0) output power is demonstrated.
