1、Zemax2003中步骤：Anaylsis-calculations-gaussianbeam中计算高斯光束传输（快捷键ctrl+B）Gaussianbeamdata-setting中初始高斯光束参数设置：M2：光束的模式，为大于1的整数，1为单基模，大于1为多模。Surf1toWaist：1面距离束腰的距离，因此一般做法是在物面和光学组前插一个1面，将束腰“放在”1面上。Divergence：远场发散角。Radius：光波的半径，束腰处无穷大。Rayleigh：瑞利长度，这三个随便一本激光原理的书里都有。目前我的一个认识：高
2、斯光束计算在zemax2003中可以也只能计算束腰尺寸，位置，远场发散角等，欢迎大家相互交流。Email:boooq@yahoo.cnbyhust—booq2008-1-26PS：没有时间翻译，在这里把Zemax里所有有关资料汇总一下，给出一个简单案例。-=-=-=-=-=--=-=-=-=-=--=-=-=-=-=--=-=-=-=-=--=-=-=-=-=--=-=-=-=-=-高斯光束Zemax介绍ComputesGaussianbeamparameters.Wavelength:Thewavelengthnumbert
