Abstract: Disclosed is an amplifying optical fiber that includes a central core that is suitable for transmitting and amplifying an optical signal and a surrounding optical cladding that is suitable for confining the optical signal transmitted in the central core. The central core is formed from a main matrix that contains nanoparticles doped with at least one rare earth element.The weight concentration of the rare earth dopants in the nanoparticles is typically between about 1 and 20 percent, and the nanoparticle concentration in the central core's main matrix is between about 0.05 percent and 1 percent by volume.The disclosed optical fiber incorporates rare earth ions at high concentrations yet avoids the phenomenon of photodarkening at high transmission power.

Abstract: Disclosed is a plasma torch for overcladding a primary preform of an optical fiber. The plasma torch includes a confinement tube for confining an induced plasma and a torch base. The torch base has a ceramic surface internal to the confinement tube. The plasma torch has extended life even at high input powers.
