SEMICONDUCTOR LASER MODULE

SEMICONDUCTOR LASER MODULE

A semiconductor laser module (10) comprises a tapered laser diode (12) and/or a tapered amplifier diode equipped with beam shaping optics (14). The tapered laser diode and/or the tapered amplifier diode includes an emission facet (16) for emitting a laser beam (18) along a beam axis (24). The beam-s...

description A semiconductor laser module (10) comprises a tapered laser diode (12) and/or a tapered amplifier diode equipped with beam shaping optics (14). The tapered laser diode and/or the tapered amplifier diode includes an emission facet (16) for emitting a laser beam (18) along a beam axis (24). The beam-shaping optics comprise a plano-convex cylindrical lens oriented so as to change divergence of the beam in the fast axis direction, the plano-convex spherical cylindrical lens having a planar surface (26) arranged facing the facet and a circular cylindrical surface (22) facing away from the facet.
