摘　　要：文章提供了一个用于对高斯光束进行拟合及匹配的软件.软件由"高斯光束拟合"和"腰斑匹配"两部分组成.对于"拟合"功能,用户只需输入测得的高斯光束光斑半径和相应的光斑位置等实验数据,即可拟合出高斯光束的腰斑半径及腰斑位置.对于"腰斑匹配"功能,输入初始光束和目标光束的腰斑半径、它们之间的距离以及用户现有的两个透镜的焦距,大约10s就能给出透镜的相应位置,即匹配方案.对于某些特定的透镜组合还可能同时给出多种匹配方式.We provide a software for curve fitting and beam waist matching of Gaussian beam.It which includes two parts：＂curve fitting＂ and ＂beam waist matching＂.For ＂curve fitting＂,the user need to type in the beam size and the corresponding position of the measured beam,and the beam waist size and position immediately by clicking ＂Fit＂aregot.For ＂beam waist matching＂,the user need to input the original beam waist size,aiming beam waist size,their distance,and two focusing length of lenses the user has,the software can give the matching position of the lenses in less than for 10 Second,i.e.the matching scheme.Moreover,It can give more than one matching scheme for some lenses combination.
