摘要 |
<P>PROBLEM TO BE SOLVED: To provide a light source device that allows easy configuration of a light-receiving element necessary for APC and realizes stable APC at a low cost. <P>SOLUTION: A light source device 6 is configured by integrally including a surface light-emission laser 1 that comprises a plurality of light sources, glass 2 as an optical element that reflects light from the surface light-emission laser 1, and a light-receiving element 3 that receives reflection light from the optical element 2. The optical element 2 is arranged so as to be inclined to a radiation direction 5 of light from the surface light-emission laser 1. When the maximum dimension of an inclination direction of light from the light-receiving element 3 represents C and the maximum dimension orthogonal to the inclination direction represents D, The relation is satisfied: C>D. <P>COPYRIGHT: (C)2013,JPO&INPIT |
