A spatial filter is an optical device which uses the principles of Fourier optics to alter the structure of a beam of light or other electromagnetic radiation, typically coherent laser light. Spatial filtering is commonly used to "clean up" the output of lasers, removing aberrations in the beam due to imperfect, dirty, or damaged optics, or due to variations in the laser gain medium itself. This filtering can be applied to transmit a pure transverse mode from a multimode laser while blockin… WebNov 17, 2024 · This work analyzes how spatial frequencies (rugate index profile optical thickness) contribute to achieve a better spectral response and considers enlargement of the rugate profile's optical thickness in extending reproduction of the expected spectral response.
