摘　　要：Through the reversible isomerization of trans-cis-trans under the linear polarization light, the molecules of azo materials have the same tropism which is vertical to the polarization of light. This means that azo materials have photo-induced birefringence which is related to optical power and polarization angle of the light. Based on the photo-induced birefringence of azo materials, we design a new type of optically pumped semiconductor vertical external cavity surface emitting laser （OPS-VECSEL） which can control the polarization and frequency of the ejection laser. The functional molecules of azo materials are [3-azo- （4＇nitro）]- （9-ethyl）-carbazole （ANECz）.Through the reversible isomerization of trans-cis-trans under the linear polarization light, the molecules of azo materials have the same tropism which is vertical to the polarization of light.
