ABSTRACT:
A light emitting device includes a semiconductor laser chip which emits a laser beam; a coherence reducing member which receives the laser beam and reduces coherence of the laser beam to generate a lower coherence light beam; and a package which houses the laser chip and the coherence reducing member, the package having an opening; wherein the laser beam emitted from the laser chip is converted into a lower coherence light beam by the coherence reducing member, and the lower coherence light beam is outputted through the opening.
