Laser power controller, laser processing device, and laser power control method

摘要

Problem to be solved: to provide a laser power controller, a laser beam machining apparatus, and a laser power control method capable of shortening the time required for measuring the power of laser light.The laser processing apparatus (1) and the laser power control apparatus (10) correspond to the measured values of the thermal radiation sensor (27) for measuring thermal radiation of the object (42) irradiated by the laser beam from the laser processing apparatus and the power value of the laser light at the working surface of the laser processing apparatus A storage unit (12) for storing data is provided.
