Enhancing 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 کاملSynchronization of Sub-picosecond Electron and Laser Pulses
Sub-picosecond laser-electron synchronization is required to take full advantage of the experimental possibilities arising from the marriage of modern high intensity lasers and high brightness electron beams in the same laboratory. Two particular scenarios stand out in this regard, injection of ultra-short electron pulses in short wavelength laser-driven plasma accelerators (1), and Compton sca...
متن کاملElectrically 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 کاملCholesteric liquid crystal devices with nanoparticle aggregation.
A broadband cholesteric liquid crystal (CLC) device with a multi-domain structure is demonstrated by using an aggregation of polyhedral oligomeric silsesquioxane (POSS) nanoparticles in the CLC layer. The aggregation pattern of the self-assembled POSS nanoparticles depends on the concentration of POSS doped in the mixture of POSS/CLC and the cooling rate of the mixture from a temperature higher...
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...
