摘　　要：通过实验数据的采集、记录,利用MATLAB软件模拟出了He-Ne激光器基模高斯光束的二维光强分布,对基模高斯光束有一个更为直观的认识.通过研究比较在不同缝宽下基模高斯光束的相对光强分布,得到缝宽越宽,光强越强.根据实验数据的测量,还利用MATLAB计算出基模高斯光束的远场发散角.The MATLAB software was used to simulate the two--dimensional light intensity distribution figure of the based--mode Gaussian beam of He--Ne laser by collecting and recording the dates. That makes people have an intuitive understanding of the base model of Gaussian beams. By means of compa- ring relative light intensity distribution under different width of seam, it was obvious that the light intensi- ty is stronger with the slit width is wider. In addition, the far field divergence Angle of the based--mode Gaussian beam was calculated through the experimental data measurement by using of MATLAB software,
