Paper Abstract

The process for Czochralski growth of convex interface Nd:YAG laser crystal with [111] seed was studied. The forming mechanisms of central core and lateral core through growth of facets were discussed. The relations between the shape of solid/liquid interface and temperature gradient in the melt and facets' growth were described. The technical methods of elimination of lateral core and reduction of central core were achieved. The good results of growth of lateral core-free and smaller central core Nd:YAG crystals were got through designing apparatus and temperature field to maintain steady growth interface pattern.
