ABSTRACT:
A method is disclosed for growing neodymium doped yttrium aluminum garnet crystals from a melt containing constituent oxides, lead oxide, lead fluoride, and boron trioxide. By subjecting the melt to a controlled temperature cycle while maintaining a temperature gradient in the melt, large size, high quality crystals are obtained. Crystals produced by the disclosed method are suited for laser application.
