Paper Abstract

We succeeded to generate tunable laser emissions from hemicyanine dye, (4-[4-(dimethylamino)stylyl]-1- dococylpyridnium bromide) doped in DNA-surfactant complex through three methods. First, we constructed Littrow type cavity containing hemicyanine and DNA-CTMA complex solutions and observed tunable laser oscillation. Next, we showed a tunable laser oscillation from ethanol solutions of hemicyanine and DNA-CTMA complex under pumping of two interfering beams which formed a distributed feedback grating of population. Finally, we fabricated a thin film composed of hemicyanine and DNA-CTMA complex, and demonstrated tunable laser oscillation under pumping with two interfering beams. We evaluated the durability of the tunable thin film laser by continuous operation, and confirmed the lifetime of more than one hour.
