Web9. aug 2024 · Atom Interferometry with Top-Hat Laser Beams. The uniformity of the intensity and phase of laser beams is crucial to high-performance atom interferometers. … In optics, a tophat (or top-hat) beam such as a laser beam or electron beam has a near-uniform fluence (energy density) within a circular disk. It is typically formed by diffractive optical elements from a Gaussian beam. Tophat beams are often used in industry, for example for laser drilling of holes in printed circuit boards. They are also used in very high power laser systems, which use chains of optical amplifiers to produce an intense beam. Tophat beams are named for their rese…
