Abstract

Owing to the intrinsic birefringence of LCs, the characteristic of random lasers (RLs) have attracted considerable attention by infilling the nematics LCs (NLCs) or polymer dispersed LCs (PDLCs), as a scattering materials, inside the glass cell, capillary tube and the hollow core fiber to produce multiple light scattering [1-3]. Unlike other scattering materials, LCs can be easily modulation through the external signals, like electric filed, magnetic field, stress, temperature and so on. Through the modulation of LCs by the temperature, the manipulation of output characteristic of RLs has been investigated previously [1-3]. In this work, the alternative characteristics from RL produced by infilling the NLC inside the single core capillary was demonstrated through the applied sinusoidal voltage and analyzed by the applied sinusoidal voltage.
