Optical beam clipping
WebOct 2, 2024 · Given that the degree of clipping is dependent on the power ratio within the surface of an optical element, the power ratio within the MSD spot range is used as a … 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. Diffraction is the deviation of light from propagating in a … See more A laser beam integrator, or homogenizer, is composed of multiple Ienslets that divide the beam into an array of smaller beams, or beamlets, followed by a lens or other focusing element that superimposes the beamlets at the … See more
