Abstract
A laser source device includes a laser source element configured to emit a laser beam, an optical element disposed downstream of the laser source element, and a return-light-receiving surface at a position shifted in a direction intersecting an active layer of the laser source element. The optical element is tilted with respect to an optical axis of the laser beam so that a return light in a form of a laser beam reflected by the optical element is incident on the return-light-receiving surface.
