La203-Al2-3-Si02 Glasses For High-Power, Yb3+ -Doped, 980-Nm Fibre Lasers

Single-mode semiconductor pumps have failed to keep pace with the increasing power requirements of Er-doped fibre amplifiers (EDFAs), so there is a need for high-powered 980-nm sources. Yb3+ -doped tapered fibre lasers can provide high-power output by conversion of a low-brightness, high-powered, 920-nm, multimode broad stripe laser diode to a high-brightness, 980-nm, single-mode output. CVD-based fibre fabrication methods are incapable of delivering fibres with an NA>~0.3 or with good efficiency at 980nm so a new method of high-NA fibre fabrication was developed.
