"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… " - Build own spatial filter laser

WebCyclops was a high-power laser built at the Lawrence Livermore National Laboratory (LLNL) in 1975. It was the second laser constructed in the lab's Laser program, which aimed to study inertial confinement fusion (ICF).. The Cyclops was a single-beam Neodymium glass (Nd:glass) laser. The Janus laser, a two-beam version of it, was also completed in … If the optical cavity is not empty (e.g., a laser cavity which contains the gain medium), the value of L needs to be adjusted to account for the index of refraction of the medium. Optical elements such as lenses placed in the cavity alter the stability and mode size. In addition, for most gain media, thermal and other inhomogeneities create a variable lensing effect in the medium, which must be considered in the design of the laser resonator.
