PROBLEM TO BE SOLVED: To adapt a system to an arbitrary waveform in the waveform control system and to give monitor information useful for quality control. SOLUTION: In this pulse laser machining device, the laser monitor part 18 is constituted of an optical sensor 34, laser output measuring circuit 36, A-D converter 38, monitor controller 40, comparing/deciding part 42, display controller 44, display 46, alarm generating circuit 48 and buzzer 50. The optical sensor 34 and the laser output measuring circuit 36 enable a laser output measurement signal (analog voltage signal) SB to be obtained that indicates the instantaneous value of the laser beam LB output, with a digital laser output measurement signal DB supplied to the comparing/deciding part 42 and the monitor controller 40 by the A-D converter 38. The monitor controller 40 sets a reference waveform for the monitor, controlling the comparing/deciding part 42. The monitor discrimination result obtained from the part 42 is displayed on the display 46 screen or the lamp through the display controller 44. |
