Coherent effects during generation and amplification in YAG:Nd and ruby have been studied at ~ 100 К for the first time. Intensity oscillations have been observed at the trailing edge of the pulse. The spectrum has a doublet structure. The transverse relaxation time T2 in ruby is estimated from the decay of the oscillations.
