Paper Abstract

We present evidence of random lasing from the fluorescent protein DsRed2. Lasing is achieved using a random 1D cavity in the simplest possible multiple scattering geometry, in which a solution containing purified DsRed2 protein placed in a layered random medium is optically excited in the direction perpendicular to the plane of random layers. Lasing was observed with both nanosecond and femtosecond pump pulses. Pumping with ultrashort pulses resulted in a lasing threshold three orders of magnitude lower than that found for nanosecond pumping.
