Abstract

The effect of self-pumped phase conjugation (SPPC) was observed recently in the inverted Nd:YAG-rod with the loop schemes.^1,2 Two possibilities of this effect realization were discussed: first is the formation of PC-wave in the resonator with the holographic mirror (RHM-scheme) induced in an inverted laser crystal by interference field of the pumping waves; second is the simultaneous stimulated resonant scattering (SRS) of two intersecting (in the general case noncoherent and cross-polarized) light beams, an incident beam and passing through the feedback loop one, in the inverted medium. This report presents a study of two SPPC possibilities for space heterogeneous laser beams in one experimental layout for the interfering and noninterfering (cross-polarized and mutually incoherent) pumping beams.
