摘要
从理论上研究了在多原子分子材料中,由激光感生的热致折射率光栅及其驰豫效应。并利用简并四波混频实验,观察了多原子分子液晶的热致折射率光栅和它的驰豫行为。
Laser-induced thermal index grating and its relaxation effect in polyatomic molecular materials have been studied theoretically.Using degenera-te four-wave mixing arrangement, we have observed thermal index grating and its relaxation in nematic liquid crystals of polyatomic molecules. The related physical mechanism is also discussed.
