Optical properties of significant acousto-optic crystals

Results of the investigation of spectra in the energy ranges of fundamental absorption of PbMoO4 crystals in two radiation polarizations (EC4) and (E⊥ C4) of incident light in the 77-300 K temperature range are presented. Possibilities of the interpretation of particularity of absorption spectra o...
