Measurement of flash-pumped M2 YAG laser at 266nm

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 file 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
