This is a picture of the resulting diffraction pattern of a He-Ne laser passing through a TeO2 AOD running at probably 35 MHz and probably about 1 Watt of drive power. It's a single AOD from an IntraAction AOD X-Y setup for 1064 nm laser light. (So, He-Ne is not the correct wavelength, and possibly the Schaefer-Bergmann diffraction is more accentuated.)
