Holographic nonspatial filters designed to clean up the output of a laser have been shown to be a great improvement over conventional spatial filters. This paper successfully addresses several major problems or shortcomings of the nonspatial filter. The problems were in the use of two filters together for cleaning up a laser beam in both dimensions. Polarization and orientation effects made the system complicated an inconvenient. A simple compound element consisting of a sandwich of two identical holograms is shown to solve these problems.
