Abstract : Chemical and structural imperfections which occur in highly transparent insulators and semiconductors were studied by a range of electromagnetic and electronic techniques. These utilized infrared wavelength modulation, high contrast Raman and Brillouin scattering and photoinduced transients spectroscopy techniques. The spectoral distribution of the absorption in the spectral region from 2.5-12 gamma was measured by infrared wavelength modulation techniques on: CaF2, LiF, NaCl, NaF, LaF3, BaF2, MgF2, SrF2, MgO, KCl, and KBr.
