Possibility of Complete Polarizational Phase Conjugation via Stimulated Brillouin Scattering

Abstract

Backward Stimulated Brillouin Scattering (SBS) is considered theoretically in the presence of birefringent inclusions that rapidly randomize polarization of propagating light. Local scalar hypersound mirrors do not conjugate polarization by themselves. However, completely conjugating specklon E(sub s)(R) = cexp(gz/2)E*(sub PUMP)(R) has better spatial overlapping with the pump profile in the presence of such inclusions. Therefore, this specklon has twice as large a gain g in comparison with all other nonconjugate scattered waves. Such gain discrimination should yield complete polarizational phase conjugation via backward SBS and thus should allow for double-pass compensation of birefringence-induced distortions introduced by laser elements. The paper includes 10 briefing charts that summarize the presentation. (14 refs.)
