Suppression of stimulated photon echo during excitation of coherent emission on an adjacent transition

A stimulated photon echo has been observed at the same time as the emission of coherent light on an adjacent transition in an LaF3:Pr3 + crystal. Excitation of the emission exactly at the resonance completely suppresses the echo signal. A theory based on the Maxwell-Bloch equations gives a good description of all the basic features of the coherent emission.
