Spatial beam apodization is a critical part of the design of high-energy solid-state laser systems. Standard methods of making apodizers include photographic and metal-vapor-deposition techniques. Apodizers fabricated with these methods are subject to damage and deterioration from high-intensity laser pulses. An alternative approach is to use a serrated-edge aperture in conjunction with the spatial filter. This system can produce beams with smooth edge profiles. We present the theory of operation of the serrated aperture along with some useful design rules and describe the successful application of a serrated-aperture apodizer in the Beamlet laser system.
