Diffractive Beam Shaper

For example a flat top beam shaper creates a far field profile with a uniform intensity in its center.

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. Diffractive diffusers are therefore ideal for laser applications in which a specific laser beam shape is required similarly to refractive homogenizers. They also allow you to realize uniform performance for a specific range at a defined distance from the light source.

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. 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. These diffractive beam shapers are available in two types top hat or stable top hat. 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.

However in contrast with the beam splitter these beams overlap and interfere generating a new homogenized distribution. Input beam diameter and profile have to be exactly right. A diffractive beam shaper allows you to modify the intensity and phase profiles of spatially coherent lasers.
