Forsterite nano glass-ceramics doped with Cr4+ ions for fiber lasers and amplifiers
Forsterite nano glass-ceramics doped with tetravalent chromium ions is synthesized, and the spectral and luminescence properties of this material are investigated. A technique for measuring the absolute quantum yield of Cr4+ luminescence is proposed and implemented experimentally. The luminescence spectra and the absolute quantum yield of Cr4+ luminescence of the forsterite nano glass-ceramics are compared with those of the forsterite single crystal and calcium aluminate glass doped with tetravalent chromium ions.
