基态精细结构能级之间的量子相干引起的非线性效应
Nonlinear effect due to the quantum coherence of the ground state fine structure energy-levels
摘要
Abstract
This paper mainly discusses the nonlinear effect induced by the quantum coherence of the ground state fine structure energy-levels in a cascade-type four-level system. Coupling field excites the optical transition from the excited state lower fine structure energy-level to both two ground state fine structure energy-levels, which leads to a new absorption peak. It is shown that the smaller population relaxation rate between two ground state fine structure energy-levels is, the more significant quantum coherence is. However, this quantum coherence can be weakened by increasing the Rabi frenquency of coupling field.关键词
