ABSTRACT:
This invention relates to an apparatus and method for providing control of high power laser/fiber delivered beam quality. Such structures of this type, generally, allow the parameters of a high power fiber delivered beam to be determined such that the high power laser beam is injected into an optical fiber with the appropriate focal length lens.
