** - according to coatings applied
piShaper transforms Gaussian or similar intensity distribution of source laser beam to a flattop one;
TEMoo or multimode with Gaussian or similar intensity profile can be applied;
Achromatic design provdes this transformation for a certain wavelength range;
Galilean design, thus there are no intermediate focusing of a beam;
With changing the size of input beam the output beam profile changes as well, see description here;
When changing the shape of input beam it is possible to adapt the piShaper to provide flattop output profile, this adaptation is realized through changing the diameter of source beam; description of this adaptation is presented here.
