摘要

实验分析了饱和吸收剂(罗丹明6G和聚甲基3274 U染料)中表现出高阶非线性的简并和非简并多波混频方案。建立了全息记录波在正交偏振处光场偏振态的空间调制所产生的偏振光栅的作用。此外，还发现绕射波的偏振与绕射顺序有关。实验实现了从红外到可见光的相干图像以及可见光区域不同波长之间的相干图像的频率转换。

Formation of polarization dynamic holograms in saturable absorbers and frequency conversion of coherent images

The schemes of degenerate and nondegenerate multiwave mixing in saturable absorbers (Rhodamine 6G and polymethine 3274 U dyes) exhibiting higher-order nonlinearities have been analyzed experimentally. The role of polarization gratings resultant from spatial modulation of the light field polarization state at the orthogonal polarization of the hologram recording waves has been established. Also, it has been found that polarization of the diffracted wave is dependent on the diffraction order. The frequency conversion of coherent images from infrared to the visible and between different wavelengths of the visible region has been realized experimentally.
