基于MATLAB的激光光束强度花样图及概率图的绘制

针对He-Ne激光器的激光输出存在多种振荡模式，不同模式下的激光光束强度不同。通过采集实验数据，得到在不同缝宽下不同振荡模式的激光光束的强度分布，利用MATLAB软件模拟出He-Ne激光光束光强分布的四种强度分布图和激光光束的概率分布云图。其中光强分布图可以直观、清晰地展示出激光光束的模型，而概率分布图则可以生动、形象地展示出激光光强的分布。

Drawing of Intensity and Probability Distribution Map of Laser Beam Based on the MATLAB

Since the output of He - Ne laser consists of various oscillation models, the light inten- sity of the beam appears difference under different model. The light intensity distribution of the beam could be obtained according to the experimental data under different gaps and oscillation models. The MATLAB software was utilized to simulate the light intensity distribution of He -Ne laser beam which contained four kinds of strength distribution map and the probability distribution map. The model of the laser beam could be clearly displayed by the intensity distribution map, while the light intensity distribution could be vividly presented by the probability distribution map.
