Abstract
PURPOSE:To produce the title single crystal of high performance for laser with good controllability by melting Nd<2>O3 or Nd2O3 and Re2O3 (Re; La, Y or Lu), LiCO3 and H3PO4, and carrying out crystallization using a formed flux LiPO3-P2O5 by a constant temp. standing method or a slow cooling method. CONSTITUTION:A NdP5O14 or (NdxRe1-x)P5O14 single crystal (where 0<x<=1 and Re; La, Y or Lu) is deposited from a melt of a compsn. Li2O-P2O5-Nd2O3 or -(NdxRe1-x)2O3. At this time, using a compsn. in LiPO3-P2O5-NdP5O3, i.e. LiPO3-P2O5 excessively added, as a flux, a good NdP5O14 single crystal is obtd. which may contain Re. The crystal is deposited at low speed by a constant temp. standing method, resulting in good crystal properties, and crystal growing rate can be controlled quantitatively by a slow cooling method.
