Abstract: The spectral selectivity of refractive-index gratings in the BaTiO3: Co crystal has been investigated. A new technique for the spectral selectivity measurement of thick reflective holograms was suggested. That technique allowed direct measurement of the spectral selectivity of gratings using a tunable wavelength laser reader. A good agreement between experimental data and theoretical calculations was obtained.
