摘要: 为了研究调整架角度误差以及波片与光源波长不匹配对线偏振光经过1/4波片之后偏振态的影响，本文利用坐标变换法得到1/4波片的琼斯矩阵，并用琼斯矩阵表示各偏振态。推导出波片与光源不匹配时对偏振态的影响理论模型。当考虑到调整架的角度误差时，对入射光偏振态以及波片的琼斯矩阵表达式做引入角度误差的泰勒展开，最后得到和实验结果匹配的仿真曲线。仿真结果表明，当采用808 nm 1/4波片对795 nm波长的线偏振光作用时，在不考虑调整误差的理想情况下出射光椭圆度最高为0.974 6，考虑调整误差时，对应理想情况下椭圆度最高为0.96，椭圆度最高点偏移1.72°。仿真和实验结果为进一步分析泵浦光椭圆度对原子参数的影响提供了依据。Abstract: In order to study the influence of the angle error of adjusting frame and mismatching of the wavelength of the light source with the wave plate on linearly polarized light after passing through 1/4 plate, the Jones matrices of 1/4 wave plate is obtained in this paper by using coordinate transformation method, and the representation of each polarization state is derived from the Jones matrix. Then the theoretical model of the influence on the polarization are deduced when wave plate and light source do not match with each other. When the angle error of the adjusting frame is considered, the Taylor expansion about the Jones matrices of the polarization state of incident light and wave plate are derived as the angle error and get the simulation curve matching with experimental result. Simulation results indicate that in the case of not considering the adjustment error, the ovality of the emergent laser is 0.974 6 when using the 808 nm 1/4 wave plate on linearly polarized light with the 795 nm wavelength; and in the case of considering the adjustment error, the ovality is 0.96 corresponding to the highest point under ideal condition as well as the highest point of the ovality offsets 1.72°. The simulation and experimental results provide the basis for further analysis of the influence of the pump light with different ovality on atomic parameters.
