Basic principles of Focal-πShaper operation:

  • Focal-πShaper is a telescopic optical systems that transforms Gaussian or similar Intensity distribution of TEM00 laser beam to the beam with Airy disk distribution providing by focusing Flat-top, "inverse-Gauss", "Doughnut" and some other profiles of the focused spot;
  • Flexible manipulation of profiles with the same device;
  • No sidelobes when optimum input beam size;
  • Optimum 2ω diameter for the Gaussian beam 4...6 mm (1/e²);
  • Low sensitivity to misalignments and beam size variation;
  • Relatively wide spectral band;
  • Optical design without internal focusing;
  • Any diffraction limited focusing lens could be applied;
  • Optimized to operate with scanning optics: mirror and polygon scanners, F-Θ lenses.

Comparison of heating of tungsten foil by:
  • a TEM01 beam focused by a lens (left column),
  • a TEM00 beam focused by a lens with a Focal-πShaper installed ahead, (right columns).
Power is stepwise increased in top-down direction.

Brightness of a dot corresponds to temperature.

One can see variation of effective beam diameter in case of non-shaped TEM01 beam (by the way with a TEM00 beam the diameter variation would be greater) and almost constant beam diameter with only variation of temperature (brightness) in case of TEM00 beam with a Focal-πShaper.
