A final report on the work accomplished during a two-year program on laser, semiconducting, and magnetic materials is presented. The laser materials studied included YAl 03Er3, SrF2Gd3, and Ce3, CdF2 Gd3, Ce3 . High-resolution optical spectroscopy and EPR studies were carried out. Electrical characteristics of the insulating and semiconducting states of the doped CdF2 system were studied and LEDs were constructed using this system. Extensive theoretical and computational studies were carried out on the YAl03 and SrF2 doped materials. An experimental facility for the evaluation of laser materials at the sponsors site was begun. The pulsed Raman technique was developed. Electrical and optical properties of ZnSe doped with Li, Cu, or Na as well as samples implanted with Zn and samples of ZnO hydrothermally grown with Li, CdS, or ZnS were studied. Also, measurements were made on radiation damaged Ge and Si. The intrinsic coercive force in multidomain single crystal rare earth Co5 alloys were studied and a model describing the observed behavior is presented.
