Abstract:The oscillating character of the intensity of phaseconjugate wave in saturable organic dye has been studied using degenerate four-wave mixing of nanosecond laser pulses, It is obseived that the law for the energy of backward phase-conjugate waves to very with the delay time of read wave offers a periodic relaxtion oscillation. The results obtained are somewhat different from that ones published in some concerned papers, Theoretical analysises show that the diffraction of grating for write waves brings about the oscillation, which the grating is formed by read wave and object wear.The oscillating period predicted theoretically is almost the same as that measured in experiment.
