Optically guided spatially modulated Laser generation with DCM dye-doped in the liquid crystal layer
Downloads
The article proposes laser-active layers that generate and reconstruct optical information through their own laser radiation. At this time, the excitation of the laser layer (optical pumping) is carried out holographically, the interference of two mutually coherent waves through the image. The II (532 nm) and III (355 nm) harmonics of the coherent emission of the Nd: YAG laser was used for holographic optical pumping of the laser layers, based on which the characteristics of the laser radiation of liquid crystal structures doped with DCM dye were studied.
