Study of ultrafast relaxation phenomena by a tunable laser induced transient grating

Li Qingxing; Yu Zhenxin

The functional relationship between the diffraction efficiency τi(⊿ω)of a tunable-laser induced transient grating and the lifetime in ith energy level is derived from the theory of three-level rate equations and Maxwell equations.In this paper,the diffraction line shape τi(⊿ω)is analyzed and discussed.The experiment result of the longitudinal relaxation time T1 associated with the S0-S1 electronic transition of Malachite Green solution is also reported.
