Absorption-mediated stabilization of nonlinear propagation of vortex beams in nematic liquid crystals

Ramaniuk, Aleksandr; Jung, Pawel S; Christodoulides, Demetrios N; Krolikowski, Wieslaw; Trippenbach, Marek


We theoretically investigate the effect of linear absorption on the stability of nonlinear vortex beams in dye-doped nematic liquid crystals. We show that the combined effects of intensity attenuation and thermal defocusing provide a stabilization mechanism which significantly extends the stable propagation distance of the vortex beam for first- and second-order topological charges.
