本文研究了近共振吸收增强的有机染料溶液中简并的四波混频作用和位相复共轭特性。由直接位相复共轭得到了高质量的再现象。再现象分辨率为6条线/毫米。对于浓度为2.5×10-5克分子若丹明6G酒精溶液,得到非线性反射率达10%。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.
