Abstract
The growth of MgO-doped single-crystal fibers of LiNbO3 by the laser h eated pedestal growth method was investigated as a function of the MgO content in the feed rods. The fibers were characterized by X-ray diff raction, optical microscopy and EDX microprobe analysis. The results a re discussed in relation to phase equilibria in the ternary system Li2 O-Nb2O5-MgO. Yb2O3 and MgO co-doped fibers were also grown and spectro scopically analyzed to study the influence of the MgO content on the l uminescence of Yb3+ ions with the aim of producing a self-doubling las er material.
