Abstract

To extend the sensitivity of photorefractive BSO crystals into the red and near-infrared part of the spectrum, they are doped with transition metals (Fe, Ni, Cr, Mn). These crystals are investigated in terms of their absorption spectra, optical activity spectra, gain coefficient in two-wave mixing, energy of holographic recording with a wavelength of He-Ne laser in diffusion, and drift recording regime.
