Investigation of erbium-doped fiber amplifier pumped by Ti:sapphire tunable laser at wavelength between 950 nm and 1000 nm

The gain characteristics of an erbium-doped fiber amplifier were investigated as a function of pumping wavelength with a Ti:sapphire tunable laser in range from 950 nm to 1000 nm. A maximum gain of 49.6 dB at 979 nm pumped wavelength and a bandwidth of 10 nm at 3 dB gain compression were obtained.
