Based on holographic lithography, layered dye-doped photonic crystals are fabricated in dichromated gelatin emulsions. Under pumping of 532 nm pulse laser, fluorescence spectrums of samples show up remarkable band gaps, and lasing is achieved at the edge of fluorescence band gap with pumping energy increasing. Furthermore, the effects on lasing of matching between the edge of band gap and the peak of fluorescence are studied. Lasing threshold becomes lower as the edge of band gap is closer to the peak of fluorescence. Otherwise, it is difficult for lasing. The study provides new idea and method for the development of super low-threshold photonic crystal laser.
