WebTop-hat beam shaper The top hat beam is used to transform a near-Gaussian incident laser beam into a uniform-intensity (flat) spot of either round, rectangular, square, line, or other shape with sharp edges in a spe-cific work plane. For good quality beam shaper performance, the laser output should be single mode (TEM 00) with an M2 value < 1.3.
