STUDY OF DEGENERATE FOUR-WAVE MIXING IN DYE-DISSOLVING LIQUID CRYSTAL IN ITS NEMATIC PHASE
掺染料向列相液晶的简并四波混频研究

Degenerate four-wave mixing effect was studied in dye-dissolving liquid crystal iu its nematic phase. Thermal grating was generated after resonant absorption of light by the dye. The anisotropy of signal and thermal grating relaxation time were also studied.
