A semiconductor laser device includes a base, a semiconductor laser element, a lid, a support member, a wavelength converting member, a holding member, and a buffer material. The lid has a recess formed in an upper portion of the lid, and a through-hole formed in the bottom of the recess. The support member is disposed in the recess and has a through-hole. A diameter of the through-hole of the support member is smaller than that of the through-hole of the lid. A coefficient of thermal expansion of the support member is different from that of the lid. The wavelength converting member is supported in the through-hole of the support member. The holding member is fixed to the lid and holds the support member. The buffer material is disposed in at least a part of a space between the lateral surfaces of the recess and the support member.

A light emitting device includes a substrate including a base member, a plurality of wiring portions disposed on a surface of the base member, a covering portion having openings respectively exposing a part of the wiring portions, a plurality of light emitting elements respectively electrically connected to the wiring portions exposed from the covering portion, and sealing members respectively sealing the light emitting elements. At least a part of the covering portion contains a light-storing material.

An optical component comprises: an optical fiber having the core and the clad; a light guide holding member attached to the exit end of the optical fiber; a wavelength conversion member that contains a fluorescent substance; and a reflection means provided between the exit end of the optical fiber and the wavelength conversion member, or between the light guide holding member and the wavelength conversion member. An increase in optical output is made possible not by reducing reflection as with conventional optical components, but on the contrary by actually producing reflection. Therefore, optical output can be increased by a means other than forming an optical film that reduces Fresnel reflection.
