The influence of the reflection coefficient on the spatial selectivity of a four-wave radiation converter in a transparent medium based on electrostriction and Dufour effect

Spatial selectivity of the degenerate four-wave radiation converter in a transparent two-component medium based on electrostriction and Dufour effect has been analyzed as a function of the reflection coefficient. The dependences of the reflection coefficient and the band half-width of spatial frequencies not reflected by such a converter on the intensity of pump waves have been shown to correlate.
