Another type of laser beam shaping is circularizing a beam, which involves converting an oval or differently shaped profile to a circular one. Laser diodes with no collimating optics will have different divergence angles in the x- and y-axes because of the rectangular shape of the diode’s active region, … See more In low-performance systems where cost is a driving factor, Gaussian beams may be physically truncated by an aperture to form a pseudo-flat top profile. This is inefficient and wastes the … See more Diffractive beam shapers utilize diffraction, rather than refraction, to shape the laser beam into a specific irradiance distribution. Diffractive elements employ an etching process to … See more So far, we have discussed shaping light using field mapping or beam integration where diffraction effects play major roles in the design and performance of the optics.
