AbstractIn this paper, we report a kind of dye-doped two-dimensional photonic crystal based on holographic polymer dispersed liquid crystals (HPDLC) with a lattice constant of 582 nm, which is prepared conveniently with a single step holographic exposure. Under the excitation of a frequency-doubled Nd : yttrium-aluminum-garnet laser operating at a wavelength of 532 nm, optically pumped lasing with narrow bandwidth and low threshold is observed from a 4-(dicyanomethylene) -2-methyl-6-(4-dimethylaminostyryl) -4H-pyran dye-doped two-dimensional photonic crystal. The results show that the emitted lasing peak is centered at about 603 nm with a full width at half maximum of only 0.4 nm, and the threshold energy is about 22. 7 mu J, which is evidently lower than the reported previously. The laser bandwidth decreases by a factor of three from 1.4 nm to 0.4 nm compared with that of the dye-doped HPDLC transmission grating. This result exhibits a bright prospect in application of tunable photonic crystal laser.
