ABSTRACT:
A laser processing device capable of recognizing a failure of pulsed laser beam irradiation during a process of pulsed laser beam irradiation and taking appropriate measures. A first judgment section and a second judgment section monitor respectively whether a pulsed laser beam is actually irradiated by an oscillation of a laser oscillator at the timing when a pulse signal is output from a pulse signal output section and whether the pulse signal output section outputs the pulse signal as setting to the laser oscillator at the timing when the pulse signal is output based on the preset pulse number. When there is a failure of the pulsed laser beam irradiation during the processing, the occurrence of failure is recognized and it can be recognized whether the failure is caused by a laser beam irradiating unit or a controller including the pulse signal output section.
