We prepare samples with different dye-doped concentrations pumped with a Nd:YAG laser at 532 nm. With an applied electric field, a tuning range of the amplified spontaneous emission of more than 20 nm was realized in each sample due to changing the effective refractive index of the nematic-liquid-crystal layer caused by the reorientation of nematic-liquid-crystal molecules. We show that there exist a threshold voltage and a saturation voltage for all the samples. With the increase in the dye-doped concentration, the peak wavelength of the amplified spontaneous emission has a red shift of about several nanometers.
