Pitch-fork hologram with topological charge of 2
Summary[edit]
| Description |
English: Pitch-fork hologram that is used to create light beams with an optical vortex whose topological charge is equal to 2. Photons of such beams carry two quanta of orbital angular momentum. Čeština: Vidlicový hologram, jenž je používán pro tvorbu světelných svazků s optickým vírem, jehož topologický náboj je roven dvěma. Fotony takových svazků nesou dvě kvanta orbitálního momentu hybnosti. |
