Abstract

Classical geometry of double phase conjugate mirror (DPCM) operation is usually associated with self-excitation of the so-called common grating which is recorded simultaneously by two separate interference patterns—of a first pump with a signal backward to a second pump, and of the second pump with a signal backward to the first one.^1,2 There was proposed also a more sophisticated DPCM model which allows generation of some intermediate fanning waves inside crystal if a particular sample demonstrates a rather high total two-wave gain.^3,4
