title: Increased photorefractive sensitivity in double-doped KTa(1-x)Nb(x)O(3):Fe,Ti.
abstract: Double-doped KTN:Fe,Ti exhibits increased photorefractive sensitivity compared with single-doped KTN:Fe and KTN:Ti. Absorption and photoconductivity measurements correlate the increase with an increased concentration of Fe in the reduced Fe(2+) valence state and to an increased fraction of Fe incorporated into the crystal from the flux.
