Paper Abstract

New phase conjugator for pseudodepolarized laser beams resulting form multiple scattering is described. The phase conjugator is based on a so-called quadric hologram, i.e., a hologram whose amplitude response contains the terms of a power series expansion on exposure degrees up to the quadratic one, recorded with a standing reference wave. Phase conjugate mirror results from an interference among partial cross-gratings associated with two components of the standing reference wave. Being read out with pseudodepolarized signal beam only, a quadric hologram generates its time-inverted twin in self-conjugation fashion. Conditions for fine polarization structure of the signal beam to be reproduced in a phase-conjugated response are discussed.
