Lasing in cholesteric liquid crystals

Cholesteric liquid crystals are periodic optical media. When doped with fluorescent dyes, they can be used to make cavity-free lasers [ 14,15]. In lasers, one of the important properties is spontaneous emission rate W, which is proportional to the density of states p, as pointed out by Purcell [16]. The density of states function is given by [Pg.84]

Materials whose dielectric properties vary periodically in space are capable of localizing photons. Such photonic band gap materials, whose structure can be regarded as a distributed laser cavity, can also lase. Cholesteric liquid crystals can act as such lasers. In addition, cholesteric elastomers can allow the distributed cavity, and hence the lasing wavelength, to be tuned by mechanical strain. [Pg.102]
