Second Order Optical Process of A Randomly Modulated Multi-Level Atom

摘要: A stochastic model of a multi-level atom interacting with its environment randomly in excited states is considered. Assuming two state-jump for the random intermediate-state interaction, analytical expressions emission spectra three- and four-level atoms second order optical process are obtained. In each case, expression shown to be separated into three types terms. Two terms correspond pure Raman spectrum luminescence, respectively, while other type term bears mixed character contributing broadening line when modulation slow merging luminescence fast. This characteristic behavior discussed use expressions.
