从理论上研究了染料掺杂双折射液晶中线性吸收对非线性涡旋光束稳定性的影响。我们表明，强度衰减和热散焦的综合效应提供了一个稳定的机制，显着扩展的稳定传播距离的涡旋光束的一阶和二阶拓扑电荷。
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.
