Abstract:

The superposition of infrared reflectivity spectra end lattice radiation of TeO/sub 2/ crystals have been investigated. Both radiation spectra at high temperatures and absorption spectra in the two-phonon range for polarizations E/spl par/c and E/spl perp/c were performed. It is shown that in the one-phonon range it is possible to reveal two-phonon bands.
