The two-dimensional distribution of saturated gain coefficient, some related physical parameters and their variation rules with the radiation intensities in a cavity are investigated in this paper. They are analysed theoretically with physical microscopic mechanism. Under three conditions or stable oscillation, the optical intensity distributions in the cavity are calculated respectively and the results are compared with each other. A simple method for selecting the optimum design parameters of a transverse laser is suggested.
