PROBLEM TO BE SOLVED: To provide a laser processing method capable of stably processing a workpiece even when the processing speed of a laser beam to the workpiece changes.SOLUTION: A laser processing method for processing a workpiece F using a laser beam B includes a step of regulating the pulse oscillation frequency of laser beam B so that the lap rate of laser beam B irradiated to the workpiece F becomes constant when the processing speed of laser beam B to the workpiece F changes, and a step of regulating the output of laser beam B so that the energy amount of laser beam B irradiated to the workpiece F per unit area becomes constant. |
