摘要	An apparatus for providing improved high power laser beams. An elongated reflector (20) with a highly reflective inner surface (26) is utilized with a laser beam emitter (22), such as a broad area diode laser, a diode laser bar, or a diode laser array. The laser beams (24) disperse and reflect off of the highly reflective inner surface (26) which is curved substantially parabolically. The inner surface (26) is coated with a highly reflective material such as aluminum or nickel. The reflected beams (28) are collimated, and can be shaped and/or coupled by manipulation of the size and shape of the elongated reflector (20) and the placement of the laser beam emitter (22) 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.
其他摘要	一种用于提供改进的高功率激光束的装置。具有高反射内表面（26）的细长反射器（20）与激光束发射器（22）一起使用，例如广域二极管激光器，二极管激光器条或二极管激光器阵列。激光束（24）从高度反射的内表面（26）分散和反射，该内表面基本上抛物线地弯曲。内表面（26）涂有高反射材料，例如铝或镍。反射光束（28）是准直的，并且可以通过操纵细长反射器（20）的尺寸和形状以及与之相关联的激光束发射器（22）的放置来成形和/或耦合。与非线性晶体结合的透镜和/或镜子系统也可用于本发明。
主权项	An apparatus for improving the quality and power of broad area diode lasers, diode laser bars, and diode laser arrays, comprising: a. an elongated reflector, said elongated reflector comprising a highly- reflective inner surface, said highly-reflective inner surface defining a hemi-parabolic curvature along the length of said elongated reflector, and said highly-reflective inner surface having a focal line corresponding to said curvature; and b. a laser beam emitter, said laser beam emitter including a plurality of laser sources capable of emitting a plurality of laser beams, said laser beam emitter being positioned in relation to the focal line of said highly- reflective inner surface such that the laser beams are emitted onto and reflected off of said highly-reflective inner surface of said elongated reflector. 2. ./ n apparatus as recited in
