Top hat laser
WebA TOP-HAT or flat-top beam shaper is an optical element that mainly applies Diffractive Optical Element (DOE). A diffractive optic (DOE) for converting a Gauss (TEM00) incident laser beam into a spot with a uniform intensity distribution with sharp edges such as circles, rectangles, rectangles, and lines on a particular machined surface.

Web18. okt 2024 · We report on the implementation of a so-called top-hat laser beam in a long-interrogation-time cold-atom interferometer to overcome the issue of inhomogeneous laser intensity encountered when using Gaussian laser beams. We characterize the intensity and relative phase profiles of the top-hat beam and demonstrate its gain in atom-optic ... WebThe most rudimentary set-up in a beam shaping system consists of a laser, a refractive / diffractive beam shaper element and a focusing lens. See the figure below. Top-hat elements have a high demand for laser quality. For good quality beam shaper performance, the laser output should be Single Mode (TEM00) with an M2 value under 1.3.
