Abstract
By changing pumping light for cholesteric liquid crystal based laser, the laser efficiency measurement of laser is done. To gain laser of high power and high efficiency, some improvement measures are proposed and tested, such as align treatment and temperature condition which also affects the wavelength of exit light. For the helical structures of cholesteric liquid crystal and its temperature-tunable characteristics, the impact of temperature is also discussed.
