Dye-doped polymer dispersed liquid crystal film was designed and fabricated, and the random laser action was studied. The mixture of laser dye, nematic liquid crystal, chiral dopant and PVA were used to prepare dye-doped polymer-dispersed liquid crystal by the method of microcapsule. Under frequency doubled 532 nm Nd: YAG (Yttrium Aluminum Garnet) laser-pumped optical excitation, a plurality of discrete and sharp random laser radiation peak can be measured in the range of 582-607 nm. The threshold of the random lasing is about 9 mJ and the line-width is 0.3-0.4 nm. The theory of ring cavity is used to prepare dye-doped cholesteric liquid crystal laser. Comparison with doped one dye polymer dispersed liquid crystal film. The experimental results show that the polymer dispersed liquid crystal film of doped different types of laser dye, it is possible to achieve broad band random lasing.
