The quality of the WFR under the four-wave interaction on thermal nonlinearity at the great reflection coefficient

It was shown that under the four-wave interaction in the thermal nonlinearity medium and taking into account thermal cell describable by first wave pumping and signal wave, second wave and object wave change of signal and object waves complex amplitude Fourier image according to its expansion may be described by homogeneous differential sextic equation. Analytic form which described completely compatibility between Fourier images of signal and object waves amplitude on the nonlinear layer fore face was received.
