Generation of High-Purity Laguerre–Gaussian Beams by Spatial Filtering
We theoretically and experimentally demonstrate that high-purity Laguerre-Gaussian beams can be efficiently obtained from Gaussian vortex beams using a typical 4F spatial filtering optical system, in which spatial filtering does not affect the spiral phase and the energy loss is very small. In the F...
