The instabilities of a nonlinear optical medium with induced absorption in a ring cavity are theoretically analyzed.Stable, bistable, and unstable stationary solutions are found for various values of incident intensity and detuning.The dynamic treatment yields, in the unstable regime, oscillations of the transmitted intensity in various modes for constant incident intensity. If the medium relaxation time is short compared with the round-trip time, oscillatory solutions are obtained, which show strong locking of the oscillation frequency to multiples of the inverse round-trip time. If the round-trip time is comparable with the medium relaxation time, numerical integrations yield periodic solutions with substructures because of the mismatch of the two characteristic times.
