高斯光束通过复杂光学系统的变换

使用矩阵光学技巧和方法详细研究了高斯光束通过复杂光学系统的传插问题。将结果推广于:(1)物像空间析射率不相等(n_1≠n_2);(2)光学系统矩阵元为复数或C元素为零的情况。就高斯限模光阑对光束传输的影响作了讨论。经典光学和高斯激光束光学(n_1≠n_2,n_1=n_2)的比较,清楚地说明了它们的区别和联系。

Gaussian beam transformation through complicated optical systems

Gaussian beam propagation through complicated optical systems is studied in detail by using matrix optics method. The results are generalized to the oases including (1) refractive indices of the object and image spaces are not the same (n1≠n2); (2) the transfer matrix elements of optical systems are complex or the element O is equal to zero. The effects of Gaissian limiting aperatore on the beam transmission are discussed. A comparison between the classical and Gaussian beam optics (n1≠n2,n1=n2) clearly illustrates their differences and relations.
