Abstract

We report a theoretical and experimental study of the amplification of femtosecond soliton pulses generated by a passively mode-locked fiber laser in a high-gain erbium-doped fiber amplifier (EDFA). Results on the spectral and temporal evolution of 450-fs soliton pulses propagating within an EDFA are presented. Power gains as high as 30 dB and the generation of sub-100-fs Raman colored solitons are observed. The results are found to be well described by the theoretical model presented.

Background-free autocorrelation trace and optical spectrum of 90-fs Raman solitons obtained at the amplifier output for a pump power of 200 mW and an amplifier length of 5 m. The spike at the input signal wavelength is due to incomplete energy transfer from the amplified input signal to the Raman soliton.
