Abstract:

We report on the research performed during the period 1982-1983 under the auspices of AFOSR. The research effort follows two directions 1 laser development subpicosecond laser, application of anti-resonant cavity to Ndglass, study of the emerald laser, and study of a new mode-locking dye for shorter pulses. 2 Time-resolved fluorescence and absorption studies of CdCr2Se4, GaAs and Ga0,5In0.5P with the goal to understand the interaction and kinetics of photogenerated carriers and basic assignments of the valence-conduction band transitions CdCr2Se4. We have also investigated the dynamics of semi-insulating CdSe. Finally we have continued the research on radiation damage neutrons and protons in CdSe and GaAs. Author
