Basic principles of piShaper 12 12 operation:

  • piShaper transforms Gaussian intensity distribution of source laser beam to a flattop one;
  • Galilean design, thus there are no intermediate focusing of a beam;
  • There are two versions of the piShaper 12_12 systems: Telescope and Collimator, please, look at the descriptions below;
  • With changing the size of input beam the output beam profile changes as well;
  • 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 12_12 for other wavelengths ranges are, also, available.
