摘要
将平顶高斯光束作为一个整体光束处理 ,研究了它通过近轴 ABCD光学系统的传输特性。对无光阑情况 ,推导出较为普遍的解析式 ;而对有光阑限制情况 ,数值积分是可行的。给出的典型数值计算结果证实了这种方法与有限拉盖尔 -高斯函数展开法是等价的。
The flattened Gaussian beam is regarded as a whole beam, and its propagation through a paraxial optical ABCD system has been studied in detail. The general closed form propagation expressions have been derived for the unapertured case, whereas for the apertured case numerical integral is applicable. Typical numerical examples have been given, showing the equivalence of this method and the finite Laguerre Gauss function expansion.
