Abstract

In this article, we present the influence of structured light on the line shape of closed hyperfine transition F=2F=3 of 87Rb-D2 line by monitoring the linearly polarized probe Gaussian beam in the presence of circularly polarized pump Laguerre–Gaussian (LG) beam having different orders of orbital angular momentum (OAM). It is observed that both the amplitude and line-width of the closed hyperfine signal under polarization spectroscopy (PS) are enhanced (reduced) with the increasing values of the pump light ellipticity for the non-zero-order (zero-order) OAM. Furthermore, the dispersion-like PS signal of the closed hyperfine transition is modified by varying the pump power and angular mismatch of the pump-probe beams. The experimental results demonstrate that the anisotropy of an atomic medium can be influenced by the OAM of light and can be further modulated by tuning the ellipticity of the structured light.

利用结构光对 87Rb-D2 线进行偏振光谱分析:控制封闭超正弦转变的线形
在这篇文章中,我们通过在具有不同轨道角动量(OAM)阶数的圆偏振拉盖尔-高斯(LG)泵浦光束的存在下监测线性偏振探针高斯光束,研究了结构光对 87Rb-D2 线的闭超频转变 F=2→F′=3 的线形的影响。研究发现,对于非零阶(零阶)OAM,偏振光谱(PS)下封闭超频信号的振幅和线宽都会随着泵浦光椭圆度值的增加而增强(减弱)。此外,通过改变泵浦功率和泵浦-探针光束的角度不匹配,闭合超频转变的色散型 PS 信号也会发生变化。实验结果表明,原子介质的各向异性可受光的 OAM 影响,并可通过调整结构光的椭圆度进一步调制。
