| 摘 要： | 使用二阶矩和广义惠更斯 菲涅尔衍射积分方法研究了用于实宗量厄米高斯光束对称化的光学系统对复宗量厄米-高斯光束的变换。研究结果表明：复宗量厄米-高斯光束经过该光学系统后，只能在出射面上实现在二阶矩定义下的对称化，但光斑不具有旋转对称性。因此，这套用于实宗量光束对称化的光学系统对复宗量光束并不适用。

| Abstract: | By using the second order moments method and generalized Huygens Fresnel diffraction integral, the optical system used for symmetrizing Hermite Gaussian beams with real argument is applied to study the transformation of astigmatic Hermite Gaussian beams with complex argument. It is shown that the second order matrix of Hermite Gaussian beams with complex argument passing through this system can be symmetrized.However, the spot shape of the beams has not a rotational symmetry . Therefore, such type of symmetrization system for beams with real argument is not suitable for beams with complex argument. |

| Keywords: | astigmatic Hermite Gaussian beam with complex argument second order matrix symmetrization. |
