ABSTRACT:
A glass-ceramic material that is doped with rare-earths and is especially suitable for lasers and optical amplifiers is disclosed. The glass-ceramic material is optically non-scattering, and the doping with rare earths is essentially in the microcrystalline phase. The glass-ceramic material is preferably made up from complexes of metals having a valency of three or greater and of halides of rare earth ions having a valency of three or greater. The rare-earth ions include an optically active rare-earth ion.
