| Abstract: | 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. |
