Abstract

Gain characteristics of an Er3+-doped fiber are investigated with different pump wavelengths using a tunable Ti:sapphire laser in the 0.98 μm band. Maximum gain was obtained at a pump wavelength of 0.980 μm and the gain profile can be fully explained in terms of the pump absorption spectrum. The 3 dB gain bandwidth for the pump wavelength was 10-14 nm. A gain coefficient of 2.6 dB/mW was obtained for a 60 ppm Er 3+-doped fiber with an absorbed pump power of 9 mW.
