Abstract
The form of the point spread function is found for a stabilized four-photon radiation converter. The functional dependence of the maximum, half-width, and phase shift at the point spread function modulus half-width on the frequency shift of the interacting waves is investigated when the focal planes of the incident and reflected waves coincide. The dependence of the resolution of a four-photon radiation converter as a function of the spectral width of the interacting waves was analyzed with the monochromaticity of these waves taken into account. The effect of the rate of change of the linear phase difference between the different components of the reflected wave on the coherent component of the point spread function was studied.
