摘要
文中采用三能级速率方程和 Maxwell 方程理论导出可调谐激光感应瞬态光栅在第 i 能级上的衍射效率η_i(Δω)与能级寿命τ_i 的关系式,并对衍射线型η_i(Δω)进行讨论和分析。同时报导了我们对孔雀绿(Malachite Green)水溶液的纵向弛豫时间 T_1的实验测量结果。
The functional relationship between the diffraction effi- ciency η_i(Δω) 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 η_i(Δω) is analyzed and discussed.The experiment result of the longitudinal relaxation time T_1 associated with the S_0-S_1 ele- ctronic transition of Malachite Green solution is also reported.
