复数矩阵元光学系统的高斯激光束传输和变换

Transmission and Transformation of Gaussian Laser Beam through Optical Systems of the Complex-matrix Elements

本文导出矩阵元为复数的光学系统输出空间高斯光束参数普遍运用的计算公式，讨论了含有高斯孔径的傅里叶变换系统和梯度折射率系统的先学传递矩阵，文中给出这些系统的光束变换式系列，表明衍射角（λ／πω＿ｇ）是高斯孔径的衍射效应因数。

The general useful calculating formulas for the Gaussian beam parameters of output space of optical systems with complex-matrix elements are derived in this paper.Optical transfer matrices of the Fourier transforming system and the GRIN system in the presence of Gaussian aperture are discussed. And a.series of thransform formulas of these systems are glven. These formulas show that the diffractive angle(λ/πω_g)is the factor of diffracting effect for Gaussian aperture.
