Abstract

A device for measuring caustic parameters of a laser beam includes a beam splitter for splitting the laser beam into at least three spatially separated partial beams, and a detection unit for detecting images of the partial beams. A beam path from an input of the device to the beam splitter defines a beam axis for the laser beam, along which the laser beam propagates until entering the beam splitter. The beam splitter includes an optical lens, and a partially reflective surface configured to split the laser beam into the at least three partial beams by partial reflection within the optical lens. The optical lens is positioned off-axis such that an optical axis of the optical lens extends off-axis to the beam axis, and/or the optical lens is tilted such that the optical axis of the optical lens forms an angle with the beam axis that deviates from 0°.
