相干耦合场作用下介质色散和吸收的改变
Change of Dispersion and Absorption in a Medium Via a Coherent Coupling Field
摘要
对V型三能级原子系统在相干耦合场作用下的吸收和色散特性进行了研究,由原子密度矩阵方程计算出原子相干生成于下两能级时介质极化强度振幅的实部和虚部,讨论了不同耦合场强度和不同非相干泵浦速率对原子系统吸收和色散的影响.
Abstract
Characters of dispersion and absorption in a V-type atom system interacting with a coherent coupling field are investigsted. The real and imaginary parts of the polarization are calculated by density matrix equations when atomic coherence between the two lower levels occurs. The influence of different coupling field intensities as well as various rates of incoherent pumping on atomic absorption and dispersion is also considered.
