Basic principles of piShaper operation:

piShaper is a telescopic optical systems that transforms Gaussian intensity distribution of source laser beam to a flattop one;
This transformation is provided for a certain wavelength range, thus piShaper is achromatic system;
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.
