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.

A measuring method for monitoring a machining operation performed by a laser, the method comprising the acts of:aiming a laser beam from the laser at a machining point; selecting as a measuring beam backscattered radiation coming from a machining site of a workpiece as a result of the laser beam,

1. A measuring method for monitoring a machining operation performed by a laser, the method comprising the acts of:aiming a laser beam from the laser at a machining point; selecting as a measuring beam backscattered radiation coming from a machining site of a workpiece as a result of the laser beam, said measuring beam having a constant correlation with the laser beam; deviating the measuring beam in a defined manner at different times and in a manner which is defined and locally mutually separate; and measuring a distribution of an energy field density of pulses or pulse groups of the measuring beam which are locally separately deviated in the defined manner.
