Self-pumped forward phase conjugator

Nery Strasman, Ron Daisy, Baruch Fischer

Abstract

A self-pumped forward phase-conjugate mirror based on nonlinear wave mixing in photorefractive media is demonstrated. A single input beam to a BaTiO3 crystal excites an oscillation of pump beams between surfaces of the crystal and a forward phase-conjugate beam. The phase conjugation is carried on the first-order diffraction from the grating induced by the input and the self-generated pump beams.
