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 a beam providing manipulation of intensity profile in area of Focus of the focusing lens;
  • Focal-πShaper can be easily (by turning one ring only!) adapted to beams of various diameters, for the Focal-πShaper_9_XXX optimum 2ω diameter range is 4-4.5 mm (1/e²);
  • Low sensitivity to misaligments and beam size variation;
  • The transformation is provided for a certain wavelength range;
  • Optical design without internal focusing of a beam;
  • Any focusing lens could be applied; the only condition is the lens to be diffraction limited one;
  • There are no limitation on applying scanning mirror heads.

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.
