Abstract
A light source device includes a substrate, a laser element on a main surface of the substrate and configured to emit laser light, an optical element on the main surface of the substrate and in an optical path of the laser light, and a polarization element on the optical element. The optical element has a first surface that reflects in a first direction a first component of the laser light incident onto the optical element from the laser element, and a second surface that reflects in the first direction a second component of the laser light incident onto the optical element from the laser element and transmitted through the first surface. The first component of the laser light reflected by the first surface is not transmitted through the polarization element and the second component of the laser light reflected by the second surface is transmitted through the polarization element.
