| 摘 要： | 本文采用二阶相干函数理论研究了V型三能级系统中三阶及五阶极化拍频(TPBVTS及FPBVTS)的非线性效应.通过对泵浦光为宽带及窄带情形的分析,我们发现三阶及五阶极化拍频信号的强度在时域内的变化取决于激光的统计特性和跃迁的横向弛豫率,从而在测量原子能级分裂时可以得到消除多普勒极限增宽的精度.另外,我们对信号的空间调制也进行了分析.

| Abstract: | The second order coherence function theory has been employed in the paper to study the nonlinear effects of third and fifth order on polarization beats in a V type three level system (TPBVTS and FPBVTS).By analyzed the cases that pump beams have either narrowband or broadband linewidth,authors found that for both cases the beat signal in TPBVTS and FPBVTS of the different temporal behavior depends on the stochastic properties of the lasers and transverse relaxation rate of the transition.Authors also found that a Doppler free precision can be achieved in the measurement of the energy level difference.The spatial modulation behavior of the beat signal has also been discussed. |
