We studied analytically and numerrically the stability of the stationary detuned modes with Gaussian transverse profile in a ring cavity containing homogeneously broadened two-level atoms. Using the mean-field and good cavity approximations, we found out unstable domain.In OBS case, we obtained conditions of optical biatability and a quadratic equation which is satisfied by the eigenvalues.
