LASER BEAM MACHINING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a laser beam machining device with which a minute part is efficiently machined. SOLUTION: The laser machining device is characterized the laser machining device with which a work is machined by a laser beam (11) provided with an ultraviolet laser beam device (1) of a synchronized injection type equipped with an unstable resonators (45 and 46), a beam condenser array (29) having plural condensers (28) each of which is arranged respectively corresponding to the arrangement of a working zone (98) of a work (37), and an optical part (25) for intensity distribution transformation which transforms the intensity distribution of the laser beam (11) into an arbitrary distribution.
