Research Abstract

Polymer laser devices attracted considerable attention for the next generation optical fibers. In this works, we focused attention on photosensitized dendrimers as a novel polymer laser medium and measured amplified spontaneous emission (ASE). The polystyrene thin films containing those dendrimers were excited by the third harmonic of pulsed Nd : YAG laser (355 nm). The emission intensities of dendrimers increased with an increase of the excitation energy. The threshold level of dendrimer having inner shell anthracene was much smaller than those of the dendrimers without inner shell anthracene chromophores. These results suggested that amplified spontaneous emission is affected by the geometry of photosensitized dendrimers.
