Abstract
A device for determining a focus position of a laser beam in a laser machining system includes an optical element configured to reflect a portion of the laser beam for coupling out a first sub-beam of the laser beam, a spatially resolving sensor to which the first sub-beam can be directed, and an evaluation unit configured to determine a focus position of the laser beam based on an actual diameter of the first sub-beam incident on the spatially resolving sensor, a laser beam power, and calibration data.
