|Abstract:||A new method for formation of singular and Bessel light beams of diﬀerent orders with the use of electrically controlled liquid crystal (LC) diﬀractive optical elements has been proposed and experimentally implemented. Formed elements are able to change the polarization and phase structure of an initial incident plane wave due to anisotropic modulation of the refractive index inside the layer of nematic LC. The orientation of LC molecules is deﬁned by previously illuminated photopolymeric layers on the substrates of LC cell.|
