Contract Crystal Growth and Fabrication Services

This program is intended to give the scientists at the Naval Research Laboratory the ability to evaluate new solid state laser crystals. The crystal requested and grown was Erbium Scandium Gallium Garnet ESGG. The melt composition is listed in Table 1. It was assumed that the distribution coefficients are unity and that the crystal composition will be the same as the melt. The crystal grew well. Some strain and surface cracking exists. The best material is in the center of the boule. No fluorescence was observed with a bright fiber optic inspection light or long wave UV source.
