Random lasing in bio-polymeric dye-doped systems

The potential for photonic application of modified deoxyribonucleic acid with cationic surfactant cetyltrimethylammonium chloride, has been shown in many fields. Here we present results of detailed studies on random lasing achieved in a biopolymer based matrix loaded with luminescent dye. The random lasing originates due to the light scattering induced by formation of nanocrystals in the bulk biosystem. We show that lasing parameters for bio-polymeric system can be comparable with similar systems based on standard or π-conjugated polymers and may contribute to commercialization of polymeric lasers
