Basic principles of piShaper operation:

piShaper transforms Gaussian or similar intensity distribution of source laser beam to a flattop one;
TEMoo or multimode input beams are accepted;
Galilean design, thus there are no intermediate focusing of a beam;
Combining of 2 functions: Beam Shaping and Collimation of a divergent beam from a fiber;
Changing the input divergence (or beam size) leads to changing of the output beam profile;
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;
Versions of the piShaper 37_34_1064 for other wavelengths are, also, available.
