Abstract

A light emitting device includes a base having a bottom part, a first semiconductor laser element disposed on the bottom part of the base, and a first light reflecting member disposed on the bottom part of the base. The first light reflecting member has a light reflecting surface configured to reflect light emitted from the first semiconductor laser element. The light reflecting surface of the first light reflecting member is a curved surface configured such that, with respect to the major portion of the light emitted from the first semiconductor laser element, the beam divergence angle of the light reflected by the light reflecting surface is greater than zero and smaller than the beam divergence angle of the light irradiating the light reflecting surface.
