Gratings
All lasers projecting a pattern other than a dot, a single line, or a crosshair have a
diffraction grating.
If your laser has a diffraction grating, use only a sterile jet of nitrogen or air to clean
the surface of the grating.

…ordinary diffraction
gratings can easily lose 50% of the energy after four reflections in a typical grating
stretcher/compressor system. To reduce this loss, special transmission gratings must be
fabricated with electron-beam lithography that add significantly to the cost. Grating
