ABSTRACT:
A processing apparatus having a laser light source for oscillating a pulse in response to a predetermined trigger signal and irradiating the beam emitted from the laser light source to an object to process the object comprises a position detection unit for detecting a position of a dimmer removably mounted in a light path of the emitted beam, and trigger control means for generating a trigger pulse train for causing the pulse oscillation type laser light source to emit light and sending out the light emission trigger pulse train to the laser light source when the position of the dimmer is within a predetermined allowable range around a predetermined target set position.
