摘要：
We report on single-pass optical gain measurements in poly(styrene) waveguides doped with polymeric model compounds under picosecond excitation. Using a wavelength-dependent model of amplified spontaneous emission, we produce optical gain spectra for these materials. Large net optical gains are produced for small input pulse energies. A figure of merit describing the potential of a material for use as a laser medium is presented. Comparisons with other recent publications indicate that organic materials can compete with inorganic semiconductors for optically pumped applications. (C) 2000 Elsevier Science S.A.
