Measurement of flash-pumped M2 YAG laser at 355nm

Images of a focused laser beam. As part of a laser M2 measurement, the laser beam shall be measured at different points of its propagation after a lens. At each measurement point 10 images were made to make averages. 10 *.txt files per position on the z-axis containing an image. Named z=xx_i.txt or xx is the position in mm and i the image number. example z=85_5.txt is the fifth image of the position 85mm. Positions are measured in relation to each other. They are not related to the position of the lens. An offset between Z=0 and the position of the lens can be set. The lens used has a focal length of 100mm本数据集收录聚焦激光束的成像结果。作为激光M²测量的组成部分，需对经过透镜后的激光束在其传播路径上的不同位置开展测量。 在每个测量点位均采集10幅图像以用于均值计算。 每个Z轴位置对应10个存储单幅图像的TXT格式文件，文件命名格式为z=xx_i.txt，其中xx为以毫米（mm）为单位的位置坐标，i为图像编号。例如z=85_5.txt即代表85mm位置处的第5幅图像。 各测量点位的坐标为相对坐标，并非以透镜位置为基准。可设置Z=0位置与透镜实际位置之间的偏移量。 本次实验所使用的透镜焦距为100毫米（mm）。
