Title
(EN) OPTICAL RESONATOR WITH SPIRAL OPTICAL ELEMENTS
(FR) RESONATEUR OPTIQUE COMPORTANT DES ELEMENTS OPTIQUES EN SPIRALE
Abstract
(EN) This invention discloses an optical resonator (24) including at least one spiral optical element (44) operative to change the angular phase distribution of modes in the optical resonator (24), thereby to generally eliminate undesirable modes.
(FR) Cette invention concerne un résonateur optique (24) comprenant au moins un élément optique en spirale (44), lequel élément permet de modifier la répartition angulaire de phase des modes dans ledit résonateur optique (24), et d'éliminer ainsi, d'une manière générale, les modes indésirables.
