Abstract: An apparatus for providing improved high power laser beams. An elongated reflector with a highly-reflective inner surface is utilized with a laser beam emitter, such as a broad area diode laser, a diode laser bar, or a diode laser array. The laser beams disperse and reflect off of the highly-reflective inner surface which is curved substantially parabolically. The inner surface is coated with a highly reflective material such as aluminum or nickel. The reflected beams are collimated, and can be shaped and/or coupled by manipulation of the size and shape of the elongated reflector and the placement of the laser beam emitter in association therewith. A system of lenses and/or mirrors in conjunction with a non-linear crystal can also be utilized with the present invention.

Abstract: Apparatus for concentrating a broad area laser beam, beams from diode laser bars and/or diode laser arrays include a collimating device disposed adjacent to the laser source for collimating and directing the laser beams into a laser beam sheet in a first direction, and a digital optics device disposed in the first direction from the collimating device for shaping and concentrating the laser beam sheet into a narrow overlapping laser beam. The concentrating device includes a pair of diffractive or digital optical devices positioned in the pathway of the collimated laser beams such that the first optical device causes the collimated beams to converge and the second optical device forms the converging beams into the desired collimated laser beam.
