Diffractive Beam Shaper

However in contrast with the beam splitter these beams overlap and interfere generating a new homogenized distribution.

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. Through in phase manipulation of the input beam you can achieve virtually limitless and most importantly speckle free intensity profiles in the output beam. A diffractive beam shaper allows you to modify the intensity and phase profiles of spatially coherent lasers. The uniform spot enables equal treatment to a surface excluding over under exposure of specific areas.

They also allow you to realize uniform performance for a specific range at a defined distance from the light source. Conventional diffractive beam shaper requires accurate alignment and beam control. The diffractive beam shaper is a diffractive optical element doe used to transform an incident laser beam into a uniform intensity spot with a well defined size and shape and with sharp edges on a specific work plane. Holo or diffractive beam shapers are diffractive optical elements doe that transform laser beams with a nearly gaussian profile into a defined 2d shape with uniform intensity distribution at the focal point of a lens.

Beam shaper is a diffractive optical element that modifies the intensity distribution of the beam. Diffractive diffusers are therefore ideal for laser applications in which a specific laser beam shape is required similarly to refractive homogenizers. These diffractive beam shapers are available in two types top hat or stable top hat.
