提出了一种将猫眼腔氦氖激光器与马赫曾德尔干涉仪相结合、通过模式叠加生成多种轴对称线偏振矢量光束的新方法。利用猫眼腔激光器获得了TEM00、TEM01、TEM10、TEM11、TEM20、TEM21、TEM30、TEM31等多种激光横模；利用马赫曾德尔干涉仪通过模式叠加获得了四种不同形式的轴对称线偏振矢量光束，其偏振级次和初始偏振方位角分别为(+1，0°)、(+1，-90°)、(-1，0°)和(-1,90°)；测量了生成光束经过线偏振片的强度分布，验证了生成光束的偏振分布特性。利用该方法可在同一系统上通过调制猫眼腔激光器生成多种形式的轴对称线偏振矢量光束，无需特殊光学元件，成本较低，操作简单。

A novel method based on a cat-eye cavity laser and a Mach-Zehnder interferometer is presented to generate various axially symmetric linearly-polarized vector beams (ASLPVB) by modes superposition. Transverse modes of TEM00, TEM01, TEM10, TEM11, TEM20, TEM21, TEM30 and TEM31 are obtained by adjusting the cat-eye cavity laser. And then, four kinds of ASLPVB, whose polarization orders and initial azimuthal polarization angles are (+1，0°), (+1，-90°), (-1，0°) and (-1,90°) respectively, are further achieved by modes superposition using the Mach-Zehnder interferometer. The transmitted intensities of generated beams passing through a linear polarizer are further measured using a CCD, which verify the polarization properties of generated vector beams. Various forms of ASLPVB can also be generated using such method in one system, which does not need special optical components, costs least and operates easily.
