Abstract
A light emitting apparatus includes: a light emitting element configured to emit laser light; a case configured to house the light emitting element, and including a window configured to allow transmittance of the laser light emitted from the light emitting element; a first optical element provided outside the case and configured to converge, in a fast axis direction, the laser light passing through the window; and a second optical element configured to collimate the laser light input via the first optical element, in the fast axis direction, in a state where a beam width in the fast axis direction is narrower than a beam width in the fast axis direction on an incident surface of the first optical element, the second optical element being located closer to the first optical element than a convergence point of the laser light in the fast axis direction by the first optical element.
