Abstract
Phosphate laser glass compositions which include erbium ions as the active laser ion material. In one aspect, ytterbium, chromium and cerium ions are present as auxiliary dopants. The ytterbium, chromium and cerium additives serve to sensitize the erbium-doped phosphate glasses of the present invention. The glasses are particularly useful in applications where an 'eye-safe' wavelength is desirable.
