从实验和理论上研究了不同空间相干度的光在近共振原子气体中的传输特性。实验结果表明,在一定条件下,部分相干光束与原子相互作用后,其相干性比与原子相互作用前有较大提高。用光谱吸收法对实验结果进行了理论解释。此外,部分相干光比完全相干光具有更好的环境适应性。
The characteristics of the light with various degrees of spatial coherence traveling in near-resonant atomic gas are investigated both experimentally and theoretically. The experimental results show that the coherence of partially coherent beams can get better after interaction with atoms under some certain conditions compared with that before interaction. The experimental results are explained theoretically by the method of spectroscopy absorption. Furthermore, partially coherent light has a better environmental adaptability than fully coherent light.
