摘要

Method for measuring the power of a laser beam (2) at different measuring points (M1, M2, M3) along a beam path from a laser generator (4) up to the processing surface (4) of a laser processing machine (5) comprises using recorders for laser power measuring devices arranged in the different measuring points in the beam path and transferring the power measurement values to a central recording unit (8, 9). An independent claim is also included for a measuring device (1) for carrying out the above method.
