Theoretical research on the random lasing from two-dimensional anisotropic media consisted of liquid crystal and mixed dye
The random lasing action in two-dimensional random media is investigated by simultaneously solving Maxwell’s equations and rate equations of electronic population. The random media are composed of scattering liquid crystal (LC) particles and mixed dye materials. The anisotropic scattering LC particl...
