摘要

We successfully fabricated a dispersion-shifted 20-um-core LMA fiber by incorporating four resonant side cores. This fiber was designed to operate at 1640-nm eye-safe wavelength and has been used in a pulsed Raman amplifier to overcome modulational instability. A peak power of 100-kW was obtained from the Raman amplifier.
