Abstract
PURPOSE: To make it possible to coat both resonance surfaces of a semiconductor laser element with a dielectric film by encabling the base body of a heat sink, stem, etc., where the element is fitted, to rotate on its junction part and also by arranging a relay terminal.
CONSTITUTION: Heat sink 20 on which semiconductor laser element 10 is mounted is made of copper block 21; screw hole 22 is made at its center part and metal 23 for strainless contact such as Mo is bonded to the mount surface of element 10. In addition, stem 30 is provided with fitting pedestal 31 of fixing sink 20, fitting screw 32 inserted into screw holw 22 of sink 20, and bonding pedestal 33 for a core wire, and the entire surface is plated with gold. Then, element 10 and lead-wire relay terminal 40 are anchored together by fusing while the center line is slid on sink 20 and screw 32 is set into screw holw 22 to fix sink 20 to stem 30. Next, the whole body is taken into a vapor-deposition unit, where sink 20 is turned around screw 32 to apply dielectric films 42 and 43 of SiO2, etc., to both resonance surfaces by turns.
