摘要: 用频域Collins公式和汉克尔变换研究了平顶高斯光束、贝塞尔超高斯光束以及拉盖尔高斯光束的传输特性,并与空域Collins公式计算结果作了比较,同时讨论了该方法的优点。Abstract: Based on the Collins formula in the frequency-domain and Hankel transform,propagation properties of flattened Gaussian,Bessel-super-Gaussian and Laguerre-Gaussian beams are studied.The results are compared with those obtained by means of the Collins formula in the space-domain,and the advantage of the method is discussed.
