【Abstract】 The mechanisms of producing central core and lateral core through growth with facets in YAG crystals were discussed. The relations between solide liquild interface shape and temperature gradient in the melt and facets growth were described. The technical methods of eliminating lateral core and reduction central core in crystal were revealed. And the lateral core free and small central core Nd:YAG crystals were grown.更多还原
