DEGENERATE FOUR-WAVE MIXING AND PHASE CONJUGATION IN ORGANIC DYE SOLUTIONS
在有机染料溶液中简并的四波混频作用和位相复共轭

Phase conjugation of forward-wave produced by degenerate four-wave mixing by using nearly resonantly enhanced nonlinearity in orgnic dye solutions. was investigated. Good-quality reconstructed images have been obtained by direct wave-front phase conjugation. Reconstructed images with a resolution of 6 lines/mm were obtained. For rhodamin 6G in alcolol solution of 2.5×10-5 mole, nonlinear reflection coefficient up to 10% has been obtained.
