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.
