Abstract

A method and system for monitoring and documenting a laser machining operation is provided. A measuring beam is generated which is correlated with the laser beam and which is deflected as partial beams transversely to its initial propagation direction. The partial beams are locally mutually separated. The distributions of the energy field density of the deflected partial beams of the measuring beam are measured.
