OPTICAL BISTABILITY BASED ON THE BAND MODEL IN A DYE RING CAVITY WITH GAUSSIAN TRANSVERSE PROFILE
具有高斯横向分布的环形染料腔中带模型下的光学双稳性

The optical bistability in a dye ring cavity laser was investigated by using the theory of band model. In the study, the real distribution of the cavity field with Gaussian transverse profile was used. The result was compared with those which were obtained by using plane wave approximation based on the band model and the two level model in one transverse mode approximation, respectively.
