Spiral spectrum of photons generated by SPDC process
Summary
[edit]
| Description |
English: A typical spiral spectum is shown, which is a probability distribution for different modes of orbital angular momentum generated by the process of spontaneous parametric down-conversion. Čeština: Vyobrazeno je typické spirální spektrum, což je rozdělení pravděpodobnosti pro různé módy orbitálního momentu hybnosti generované procesem spontánní parametrické sestupné konverze. |
