基于铯原子基态的超精细能级与激发态的两个超精细能级构成的V型三能级系统,对不同温度下铯原子汽室内的EIT效应与缓冲气体分压之间的依赖关系进行了实验研究,得出由dephasing诱导干涉的物理机制是受激辐射与自发辐射的竞争。
We experimentally research the relationship between EIT effect and buffer gas pressure at different temperatures in cesium atomic vapor in V-type three-level system based on a hyperfine level of the ground state and the two hyperfine levels of the excited state. The results indicate that the physics behind the dephasing-induced control of interference is the competing between stimulated emission and spontaneous emission.
