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.

Abstract: A light source unit includes a red light source, a first blue-light source, a fluorescent material, a second blue light source and an optical system. The red light source emits light in red wavelength range. The first blue-light source emits light in a first blue-wavelength range. The fluorescent material receives the light in the first blue-wavelength range and emits light in a green wavelength range. The second blue-light source emits light in a second blue-wavelength range whose wavelengths are longer than those in the first blue-wavelength range. An optical system guides the light emitted from the red light source, the light emitted from the second blue-light source, and the light emitted from the fluorescent material, along a unique optical path.
