Abstract

Geometry for conjugation of mutually incoherent laser beams, consisting of two interconnected passive ring mirrors, was proposed in Ref.[1]. This is the only geometry among all known mutual conjugators, that can work equally well with either transmission, or reflection gratings recording. A detailed theory of this geometry and its experimental realization in the photorefractive SBN crystal in the case, when transmission gratings were operating, can be found in Ref.[1]. Here we report on the experimental investigation of a reflection grating mutual conjugator in the geometry of two interconnected ring mirrors in cw regime with the characteristic relaxation times of the order of several milliseconds.
