Abstract
A novel scheme for generation of laserlike emission from highly scattering media is presented. A high degree of directionality is obtained owing to the excitation of surface plasmons in a silver film. The electromagnetic energy coupled to surface plasmons is transferred to a polymeric disk containing Rhodamine and nanospheres placed in close contact with the film. The fluorescence produced in the disk, outcoupled through a prism, displays features of a “laser paint” plus a high directionality.
