  • Method for identifying the power output by a laser onto a workpiece
    Patent number: 4818841
    Abstract: A method for identifying laser power evaluates the sound emission signal arising in a workpiece during processing and represents the power of the laser. A calibration curve is established through a plurality of measuring points and is linearized over certain regions to assign a defined power to each mean frequency of the sound emission signal. Undesired deviations of the power can be identified, without problem, by introducing defined tolerance limits of the registered frequency.
