In this paper, we investigate Yb doped Y2O3 (or Y3Al6O12) nanoparticles in a silica rich matrix, as an alternative to the Yb in a 'standard', such as aluminium or phosphorous co-doped, silica host for use in high power fiber lasers. Y2O3 is a good host for RE incorporation, and efficient Yb:Y2O3 ceramic lasers have been reported. It is expected that Y2O3 nanoparticles within a silica host will improve...
In this paper, we report preliminary results for a Ho silica fibre laser operating at 2090 nm in-band pumped by a cladding-pumped Tm doped fibre laser at 1980 nm. The Tm fibre pump laser was constructed in-house with wavelength selection provided by an external cavity containing a diffraction grating. This could produce over 20 W of output at 1980 nm (corresponding to the absorption peak in Ho-doped...
