摘　　要：矢量光场在其传输和与物质相互作用过程中,光场状态的时空演化区别于传统偏振光,具有独特的矢量化特征。研究了晶体二氧化碲(TeO_(2))对于径向偏振矢量光场的调控特征,通过斯托克斯参量的测量,分析了3个晶体样品的偏振态演化规律,揭示了TeO_(2)晶体的旋光特性,表明其可以起到和双λ/2波片相同的偏振调控效果。研究结果有助于理解矢量光场在双折射晶体中的传输特性,促进矢量光场相关晶体器件的设计与应用。In the process of transmission and interaction with substance,the vector light field with spatiotemporal evolution of light field state is different from the traditional polarized light.It has the unique vectorization characteristics.The regulate and control characteristics of crystal tellurium dioxide(TeO_(2))for radial polarized vector light field was utilized to study.According to the measurement of Stokes parameters,the evolution laws of polarization state of three crystal samples were analyzed,and the optical rotation characteristics of TeO_(2)crystal were revealed.It showed that the polarization regulate and control effect could be considered as same as doubleλ/2 wave plate.The research results are helpful to understand the transmission characteristics of vector light field in birefringent crystals,which can promote the crystal device design and application in connection with vector light field.
