Raman spectra of lithium niobate single crystals strongly doped by zinc and magnesium, it
has been established, contain low-intense bands with frequencies 209, 230, 298, 694, and …

Photoinduced light scattering and optical spectroscopy have been used to study the
photorefractive effect and determine the band gap in nominally undoped congruent and …

An iron-doped Y-cut lithium niobate (Fe: LN) slab was coated with indium-tin-oxide (ITO) thin
films by magnetron sputtering. The electron confinement in a sub-nanometer region at …

indium-tin-oxide (ITO) films coated on iron-doped lithium noibate (LN) slabs. Surface …

By indicatrix parameters' of photoinduced light scattering (PLS) photovoltaic and diffusion
fields in Lithium Niobate crystals of different composition are determined. It is shown that …

Experimental study of non-linear scattering (NLS) in nominally pure, Mg-and Zr-doped
LiNbO 3 crystals with a varying dopant concentration are reported in this paper. The study is …
