Title:
LASER PROCESSING DEVICE AND LASER PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2022062738
Kind Code:
A
Abstract:
To recover laser power in a method other than adjustment of an optical system when the power is lowered in a processing spot in a laser processing method in which a laser pulse emitted from a laser oscillator is radiated to a workpiece to process the workpiece.SOLUTION: A laser processing device includes: an optical sensor for measuring power of a laser pulse in a processing spot; and a timing control unit which determines a delay time of an oscillation cycle of the laser pulse when the power measured by the optical sensor is lower than a predetermined value. A laser oscillation control unit delays the oscillation cycle of the laser pulse by the time determined by the timing control unit when the power measured by the optical sensor is lower than a predetermined value.SELECTED DRAWING: Figure 3
