Abstract
A laser beam mixer combines two or more input laser beams in a coaxial manner to provide an output beam. At least one of the input beams is altered in cross-sectional profile, for example, to an annular cross-sectional shape. Another input beam is placed within the altered beam by a beam combining element having a transmissive portion and a reflective portion to respectively reflect and transmit the two input beams. The beams are combined with minimal beam losses and without diverging a beam profile.
