Abstract

The laser heated pedestal growth (LHPG) technique has been used to grow miniature crystals of the mixed niobates, RETiNbO6 with RE = Nd, Pr and Er, having typical dimensions of 0.5 mm diameter and 10 mm in length. The Nd and Pr compounds grow in the aeschynite structure, whereas the Er compound grows with the euxenite structure, The crystals grown by the LHPG technique were characterised by measurement of their X-ray diffraction patterns and optical absorption and photoluminescence spectra. The latter show very high absorption coefficients for the rare earth ions and strong luminescence signals. Brief reports are presented of these spectra, and discussed in terms of the potential of RETiNbO6 single crystals as laser gain media.
