Basic principles of πShaper operation:
- πShaper transforms Gaussian or similar intensity distribution of source laser beam to a flat-top one;
- TEM00 or multimode with Gaussian or similar intensity profile can be applied;
- Achromatic design provdes this transformation for a certain wavelength range;
- Galilean design, thus there are no intermediate focusing of a beam;
- There are two versions of some πShaper 6_6 systems: Telescope and Collimator, please, look at above descriptions;
- 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 πShaper to provide flat-top output profile, this adaptation is realized through changing the diameter of source beam; description of this adaptation is presented here.
