主　　题：Distributed Bragg reflectors Mirrors 

摘      要：An intracavity frequency-doubled vertical external cavity surface emitting laser （VECSEL） with green light is demonstrated. The fundamental frequency laser cavity consists of a distributed Bragg reflector （DBR） of the gain chip and an external mirror. A 12-mW frequency-doubled output has been reached at 540 nm with a nonlinear crystal LBO when the fundamental frequency output is 44 mW at 1080 nm. The frequency doubling efficiency is about 30%.
