Quantum-efficiency measurements in oxygen-containing gallium lanthanum sulphide glasses and fibers doped with Pr(3+)

The production of competitive fiber amplifiers in the 1.3-mum region requires both good quantum efficiency in the lasing ion and the capability to produce low-loss fibers. Oxygen-doped gallium lanthanum sulphide (GLS) doped with Pr(3 ) may provide a route to both, We describe measurements of the qua...
