When the frequency of a circularly polarized electromagnetic wave is equal to the atomic frequency, the atom lifetime of tow level atom is not influenced by the electromagnetic wave. For a ∧ type three level atom in a circularly polarized electromagnetic wave, we modulate the frequency of the electromagnetic wave to study the atom lifetime and show that the approximate condition in this paper is rational. 圆极化光 二能级原子 ∧-型三能级原子 原子寿命 circularly polarized electromagnetis wave two-level atom ∧ -type three level atom atom-lifetime 10.14188/j.1671-8836.2000.03.024 O562 湖南师范大学科研基金资助项目 2000-03-01 2021-04-01 3
