Abstract
A method for adjusting a beam caustic of a laser beam generated by a laser beam unit is provided. The laser beam unit includes an optical device. The method includes ascertaining three beam diameters of the laser beam at three measurement planes positioned along a laser beam propagation direction, determining the beam caustic of the laser beam by analytically calculating beam propagation parameters of the laser beam based on the three ascertained beam diameters, ascertaining a laser beam deviation by comparing the beam caustic with a target beam caustic of the laser beam, and adjusting the laser beam unit based on the ascertained laser beam deviation.
