Title:
LASER DEVICE, LASER PROCESSING MACHINE, AND METHOD FOR CONTROLLING OUTPUT OF LASER DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/215798
Kind Code:
A1
Abstract:
A laser device (100A) comprising a plurality of laser modules, wherein the laser device (100A) comprises: a plurality of drive power source units that drive the laser modules; a plurality of output detection units that detect the laser outputs from the laser modules, and output the detection values as first output signals; a coupling output detection unit (55) that detects the total laser output after coupling the plurality of laser outputs, and outputs the detection value as a second output signal; a calculation unit (1A) that, using the plurality of first output signals and the second output signal, sets a plurality of output correction rates that control each of the laser modules; and a control unit (2A) that controls the plurality of drive power source units using the plurality of output correction rates, each of the plurality of output correction rates being set so that the total laser output reaches a fixed value.
