Abstract
A laser system for directing an output laser beam onto a work piece is provided. The laser system includes a main housing. A laser source is provided for generating an input laser beam. A cylindrical housing is supported for angular rotation within the main housing. The cylindrical housing includes an input aperture at a first end for receiving the input laser beam and a reflecting mirror at a second end for directing the input laser beam through an exit aperture. An annular mirror is supported within the main housing. The annular mirror receives the input laser beam directed through the exit aperture for generating the output laser beam. The output laser beam has an annular cross section.
