<P>PROBLEM TO BE SOLVED: To achieve the positioning of a hologram element at a high speed and with high accuracy. <P>SOLUTION: This adjusting method of a semiconductor laser device is an adjusting method of a semiconductor laser device which performs the positioning of a light receiving element 20 and a hologram element 17 by passing the laser beam 16 emitted from a semiconductor laser element 15 of the semiconductor laser device in which the hologram element 17 is mounted in the upside of a package which is equipped with the semiconductor laser element 15 and the light receiving element 20 through the hologram element 17, a collimating lens and an objective lens, and by receiving the return light 18 of the laser beam reflected by a reflective mirror with the light receiving element 20 and the adjusting method adjusts the positioning of the light receiving element 20 and the hologram element 17 by dividing the light receiving element 20 into a plurality of light receiving areas 21 and by receiving the return light of the laser beams with respective light receiving areas 21 and by moving the hologram element 17 so that received light quantities of the respective light receiving areas 21 become optimum ratios. Since the hologram element 17 can be adjusted simultaneously in the X direction and the Y direction, adjusting time can be shortened. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
