ABSTRACT:
This specification discloses a beam shaping optical system for treating the diverging beam emitted from the exit surface of a semiconductor laser. The beam from the semiconductor laser has different angles of divergence and different origins of divergence in directions orthogonal to each other. Such a beam may be collimated or efficiently treated into a circular spot light by the beam shaping optical system.
