Abstract: A lasing device includes an active layer comprising a cholesteric liquid crystal material and a laser dye, and a liquid crystal cell including spaced apart substrates defining a cell gap in which the active layer is disposed. The substrates include electrodes arranged to bias the active layer into an oblique helicoidal (ChOH) state. At least one substrate of the liquid crystal cell is optically transparent for a lasing wavelength range of the device.

Abstract: The present invention provides a compound represented by the general formula (I), and a polymerizable composition containing the compound. When the polymerizable composition containing the compound represented by the formula (I) is used to form a filmy product, the resulting filmy product exhibits less change over time in phase difference and reverse wavelength dispersion and when the filmy polymer is irradiated with UV light, peeling from a substrate is unlikely to be caused. Further, the invention provides a polymer obtained through polymerization of the polymerizable composition and an optically anisotropic body obtained using the polymer.
