The interaction of a sufficiently intense 0{pi} pulse with the inhomogeneously broadened resonance quantum transition is studied numerically in the slowly varying envelope approximation. The formation of a single optical breather and evolution of the population of energy levels related to it are described. It is found that in the quasi-resonance case, two 2{pi} pulses of the same duration with different frequencies appear instead of the breather at a large distance. The frequency modulation also prevents the formation of the breather, giving rise to one 2{pi} pulse or two 2{pi} pulses of different frequencies and different durations. The results of numerical analysis of the known experiment on the observation of the 0{pi} pulse in a ruby crystal are presented. It is shown that due to the presence of irreversible relaxation in this experiment, an optical breather was detected at the stage of its transformation to a weak 0{pi} pulse.
