  • Publication number: 20230088006
    Abstract: A light source device includes a laser diode, a focusing mirror, a focusing lens, and an optical fiber. The laser diode emits a laser beam having a divergence angle in a first axial direction of a first axis perpendicular to an optical axis larger than a divergence angle in a second axial direction of a second axis perpendicular to the optical axis and the first axis. The focusing mirror reflects the laser beam emitted from the laser diode and focuses the laser beam in the first axial direction. The focusing lens focuses the laser beam reflected by the focusing mirror in the second axial direction. The optical fiber has a core that the laser beam focused by the focusing mirror and the focusing lens enters.
