Paper Abstract

Watt-level Bi fiber lasers have been demonstrated at 1280, 1330, 1340, 1360 and 1480 nm with the maximum output power of up to 10W and with the efficiency of up to 50% for the first time. The bismuth-doped phosphogermanosilicate fiber amplifiers operating within the wavelength range 1300-1500 nm have been developed. The net gain of more than 20 dB at the wavelengths of 1320 and 1440 nm under the 200-300 mW pump power was obtained. The 3 dB bandwidth of the amplifiers was larger than 30 nm, the noise figure being 4-6 dB.
