Abstract
Three new laser lines are reported: Two lines, at 1.0448 and 1.0661 μ, occur for a CaF2 crystal which is heavily doped with NdF3; a line at 1.0336 μ occurs for a CaF2 crystal containing NdF3 and YbF3. Details of the absorption and fluorescence spectra indicate that the laser oscillations arise from Nd3+ ions at noncubic sites in the first crystal and from Yb3+ ions in the second crystal. The growth techniques are summarized; the special growth procedures minimize the oxygen content, thereby reducing the number of impurities in sites for Nd3+ and Yb3+.This publication has 5 references indexed in Scilit:
