Generation of Vector Space Light and Its Exploration in the Teaching Research of College Physics Experiment

具有空间变化偏振态的矢量空间光与热原子相互作用时会产生许多有趣的现象。本文主要是利用涡旋半波片将基模高斯光转换成具有空间偏振态分布的矢量空间光,然后再与热原子介质进行相互作用,通过改变激光场的频率、功率以及热原子的相关性质来观察矢量空间光经过热原子介质后的能量分布,结果表明相关因素对矢量空间光与热原子相互作用有着重要影响。该文对大学物理实验教学研究的探索有一定的指导意义。

There are many interesting phenomena when the vector light field with spatially varying polarization states interacts with nonlinear matter.In the experiment,the vortex half-wave plate is used to convert the fundamental mode Gaussian light into a vector light field with spatial polarization state distribution,and then interact with the hot atomic medium by changing the frequency,power of the laser and the related properties of the hot atoms to observe the energy distribution of the vector light field after passing through the hot atoms,the experimental results show that these factors have an important influence on the interaction between the vector light field and the hot atoms.Our work may have certain reference significance in studying the teaching of college physics experiment.
