Laguerre-gaussian beam wiki
TīmeklisIf the resonator symmetry is mostly circular, the modes exhibit a cylindrical symmetry described by the Laguerre polynomials. The mathematical method is the same as the one described for Hermite-Gaussian modes. The figure 21 describe the intensity distribution for such modes. Figure 21 : Spatial energy distribution for Laguerre … Tīmeklis2024. gada 22. jūl. · Spiral phase plates (SPPs) are optical devices that transform a plane electromagnetic wave to a Laguerre–Gaussian (LG) beam. The LG beam then carries orbital angular momentum (OAM) with a non-zero LG mode number that is characterized by a helical phase front with the axis of rotation along the boresight, or …
