Abstract

We analyze vectorial wave mixing in a photorefractive crystal of cubic symmetry in different geometries of beam interactions—reflection, transmission, and orthogonal. It is shown that orthogonal geometry in contrast with others supports an efficient phase demodulation of a depolarized object wave in linear mode without using any polarization-filtering elements. As a result adaptive interferometers based on the orthogonal geometry can provide a higher signal-to-noise ratio due to lower noise and lower optical losses.
