In this paper,we extend quadruple degenerate four-wave mixing into doublet degen-erate four-wave mixing so that frequency-conversion reconstructed waves which are phaseconjugation of incident object waves can be obtained. Using this method 5320 (?) objectwaves have been converted into reconstructed waves of another frequency 6300 (?). Fur-thermore, 1 .06μm infrared images have been converted into 5320 (?) visible image. Byusing a medium which is a resonant absorber for infrared object wave but transparentfor visible reconstruction wave, third-order nonlinear susceptiblity can be resonantly en-
In this paper, we extend quadruple degenerate four-wave mixing into doublet degen-erate four-wave mixing so that frequency-scaling reconstructed waves which are phaseconjugation of incident object waves can be obtained. Using this method 5320 (?) Objectwaves have been transformed into-reconstructed waves of another frequency 6300 (?). Fur-thermore, 1.06μm infrared images have been converted into 5320 (?) visible image. Byusing a medium which is a resonant absorber for infrared object wave but transparent for visible reconstruction wave, third -order nonlinear susceptiblity can be resonantly en-
