Web27. jan 2024 · What is a top hat beam? A top hat laser beam has an intensity profile that is flat and uniform, with sharp edges where the energy drops rapidly to zero. The top hat beam shape can be a square, rectangle, line, circle or any other shape. There are generally two types of top hat laser beams: collimated and waist (focus) top hats. Webtop Hat beam shaping optics typically trans-form an incoming collimated laser beam into a round or square shaped uniform intensity distribution. Refractive top Hat shapers for Gaussian (tem 00) beams are mostly freeform optics and can be designed using analytical methods based on the principle of conver-sation of energy. With this method one cal-
