In optics, a tophat beam such as a laser beam or electron beam has a near-uniform fluence within a circular disk. It is typically formed by refractive or 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 resemblance to the shape of a top
