摘要

The linear and nonlinear optical properties of commercially available CdS(x)Se(1-x) doped glasses are reviewed and the origin, magnitude and temporal response of the nonlinearities are discussed. The room-temperature carrier dynamics are analysed using femtosecond interband pump-probe measurements. Our experimental results show the evolution of the carriers into a hot, quasi-thermal plasma distribution via electron-electron and electron-phonon scattering. The quasi-thermal distribution cools to the lattice temperature in about 750 fs filling the states just above the band-edge. This band filling nonlinearity is seen as the bleaching of the absorption above the bandage. The carrier recombination lifetime is measured to be +/- 10 ps at higher carrier densities. Reprints.
