Abstract: The present invention is directed to isotopically enriched optical materials and methods of producing the same. The optical materials provide high isotopic purity silica, calcium, zinc, gallium and germanium materials with increased resistance to optical damage which can be used alone or in combination with other means of preventing damage to decrease lens degradation caused by energy-induced compaction during use.
