The distortion of a phase conjugate wave produced by degenerate four wave mixing as a consequence of thermal self-defocusing is reported. The thermally induced refractive index changes cause modulation in the phase of the phase conjugate wave. The thermal self-defocusing effect may impose a limiting factor in high repetition rate nonlinear devices.
