摘要
介绍研究氦氖激光基横模的刀口法测量原理,给出实验装置和实验结果.这种方法能够证实氦氖激光基横模的光强分布是高斯分布,能够确定光斑的大小.
The measurement principles of edge method for studying the fundamental transverse mode of He-Ne laser are introduced and the experimental set-up and results are reported. The method can confirm the Gaussian distribution of optical intensity for the fundamental transverse mode of the He-Ne laser and determine the size of its light spot.
