<P>PROBLEM TO BE SOLVED: To provide a laser diode unit for laser processing which can properly cool two laser diodes for the laser processing that are incorporated in a chamber, can maintain high oscillation efficiency of laser light of the laser diodes, and allows the usable environmental temperature to be set to a high temperature. <P>SOLUTION: In a laser diode unit 7, a peltier element 25 is laminated on an upper surface of a bottom plate 17a in a chamber 17 formed into a box shape, and laser diodes 9a, 9b are laminated to be disposed on an upper part of the peltier element 25. Further, a heat sink 27 is attached to a lower surface of the bottom plate 17a. A heat insulation layer 28, blocking heat from being transmitted from the bottom plate 17a of the chamber 17 to areas above the bottom plate 17a, is provided in the laser diode unit 7. <P>COPYRIGHT: (C)2013,JPO&INPIT |
