Abstract : An apparatus and method are provided to homogenize the intensity profile of the beam emitted by an excimer laser. The excimer laser beam is collected by a closely packed ultraviolet-grade optical fiber bundle array having its individual fibers intermingled in a random or preconceived format to result in an intermixing of the light from the individual fiber cores to produce a uniform intensity profile. The output ends of the fibers are gathered or fused, and optionally tapered; before being cleaved to provide an output face that is custom shaped for a desired illumination pattern. The flexible nature of the fiber bundle allows for remote materials processing applications. Patents. (jhd)
