The effect of the output spectrum on the beats of the oppositely directed waves in a ring laser is studied. The laser operates in the self-locking mode corresponding to the excitation of two pulses in each of the oppositely directed waves. Equations for the fields of the oppositely directed waves are analyzed. It is found that the beat signal of the oppositely directed waves depends on the phase of the field oscillations in the oppositely directed pulses. Experimentally, stable self-locking is achieved when the active medium of the laser is immersed in an axial magnetic field. Effects due to the dependence of the amplitude of the beat signal of the oppositely directed waves on the frequency to which the optical resonator is tuned are found for ''strong'' and ''weak'' coupling of the longitudinal modes. These effects are explained.
