Abstract
A length of an absorbing optical fiber is connected to receive light output from an optically pumped light source. The light source includes a gain fiber that is doped with erbium. Pumping the erbium with a pump wavelength of 980 nm causes the erbium to emit light having a wavelength of 1550 nm. Ytterbium ions in the absorbing fiber attenuate light having the pump wavelength without affecting the intensity of the 1550 nm light output from the erbium in the gain fiber.
