Reconstruction of the spatiotemporal distribution of the effective reflectance of a phase-conjugate mirror from the oscillograms of incident and reflected pulses

The spatiotemporal characteristics of nonlinear optical adaptive processes with the use of the effective reflectance of a phase-conjugate (PC) mirror based on the stimulated scattering of light or three-wave mixing are considered. The efficiency of the use of this physical parameter for studying the characteristics of PC mirrors in the case of inertialless nonlinearity is demonstrated by the example of phase conjugation of magnetostatic waves.
