Diffractive Beam Shaper

Through in phase manipulation of the input beam you can achieve virtually limitless and most importantly speckle free intensity profiles in the output beam.

Diffractive beam shaper.

Beam shaper is a diffractive optical element that modifies the intensity distribution of the beam. 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. 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.

They also allow you to realize uniform performance for a specific range at a defined distance from the light source. For example a flat top beam shaper creates a far field profile with a uniform intensity in its center. The uniform spot enables equal treatment to a surface excluding over under exposure of specific areas. A diffractive beam shaper allows you to modify the intensity and phase profiles of spatially coherent lasers.

Diffractive diffusers are therefore ideal for laser applications in which a specific laser beam shape is required similarly to refractive homogenizers. Conventional diffractive beam shaper requires accurate alignment and beam control. 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.
