Abstract
The imaging properties of wave-front reversal with nonlinear probe dependence and large frequency conversion are investigated. A calculation is made of the field generated by an arbitrary probe field distribution. It is found that a phase-matching problem, similar to that in nondegenerate four-wave mixing, limits the spatial resolution. Lensless imaging is shown to be impossible because of the nonlinearity of the process. The use of the process as a frequency-converting mirror in a conventional imaging system is studied with diffraction theory. Aberrations in such a system cannot be compensated by a phase-conjugate mirror with large frequency conversion.
