LASER DIODE MODULE, LASER DEVICE, AND LASER PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a laser diode module which is capable of outputting a laser beam stably for a long term, to provide a laser device using the laser diode module, and to provide a laser processing device. SOLUTION: Sub-mount boards 602 are each bonded on both the surfaces of a laser diode 601 through the intermediary of a hard solder layer 603. The lower sub-mount board 602 is bonded to a heatsink 605 with a soft solder layer 606. The heatsink 605 and a pressing electrode 608 are fixed through the intermediary of an insulating spacer 609 separately from each other by a prescribed space. A coil electrode 607 is fitted into a V-shaped groove cut in the pressing electrode 608, and the coil electrode 607 is elastically deformed a little so as to be pressed against the upper sub-mount board 602.
