摘要：

A theoretical study is made of the ″mosaic″ regime of wavefront reversal in stimulated backscattering of a pump beam with a small-scale spatial inhomogeneities. The scattered field mainly takes the form of the reversed pump field with a continuously varying (mosaic) envelope. For statistically homogeneous pump radiation the solution shows transverse enhancement of the coherence of the envelope up to a radius which depends on the length of the medium. The mosaic-induced angular scatter of the beam reconstructed in wavefront reversal through a phase plate is discussed.
