Electrically tunable laser based on oblique heliconical cholesteric liquid crystal.
A cholesteric liquid crystal (CLC) formed by chiral molecules represents a self-assembled one-dimensionally periodic helical structure with pitch [Formula: see text] in the submicrometer and micrometer range. Because of the spatial periodicity of the dielectric permittivity, a CLC doped with a fluorescent dye and pumped optically is capable of mirrorless lasing. An attractive feature of a CLC l...

متن کاملEnhancing cholesteric liquid crystal laser performance using a cholesteric reflector.
A high performance dye-doped cholesteric liquid crystal (CLC) laser is demonstrated by incorporating a passive CLC reflector to the active cell. The polarization-conserved CLC reflector effectively increases the distributed feedback cavity length which, in turn, results in a significant enhancement in lasing efficiency and a dramatic reduction in beam divergence. The lasing characteristics are ...
متن کاملCholesteric Liquid Crystal Flakes—a New Form
LLE Review, Volume 74 139 The last 20 years have seen a growth of mixed-media systems in which cholesteric liquid crystals (CLC’s) are one component. These include polymer-dispersed CLC’s1 in which the CLC’s are confined to microdroplets within a continuous isotropic polymer and CLC’s in gels2 in which there is a small amount of polymer to stabilize the CLC structure. In either case, the contin...
متن کاملColloidal cholesteric liquid crystal in spherical confinement
The organization of nanoparticles in constrained geometries is an area of fundamental and practical importance. Spherical confinement of nanocolloids leads to new modes of packing, self-assembly, phase separation and relaxation of colloidal liquids; however, it remains an unexplored area of research for colloidal liquid crystals. Here we report the organization of cholesteric liquid crystal for...
