Diffractive Beam Shaper

A top hat beam shape r also known as flat top beam shaper is the high end option applicable for laser systems that use single mode low m 2 laser beams typically m 2 1 5.

Diffractive beam shaper. Conventional diffractive beam shaper requires accurate alignment and beam control. For example a flat top beam shaper creates a far field profile with a uniform intensity in its center. They also allow you to realize uniform performance for a specific range at a defined distance from the light source. Through in phase manipulation of the input beam you can achieve virtually limitless and most importantly speckle free intensity profiles in the output beam.

The uniform spot enables equal treatment to a surface excluding over under exposure of specific areas. Diffractive diffusers are therefore ideal for laser applications in which a specific laser beam shape is required similarly to refractive homogenizers. A diffractive beam shaper allows you to modify the intensity and phase profiles of spatially coherent lasers. A flat top laser beam shaper is a diffractive optical element doe that transforms the gaussian beam into a flat top beam with uniform intensity inside a well defined shape with pre designed angular dimensions and a.

However in contrast with the beam splitter these beams overlap and interfere generating a new homogenized distribution. Beam shaper is a diffractive optical element that modifies the intensity distribution of the beam. These diffractive beam shapers are available in two types top hat or stable top hat.
