Limitations Imposed by Stimulated Raman Scattering on 1550 nm High-Energy Pulse Transmission
Several applications have been proposed that transmit high-energy 1550 nm pulses over optical fiber. These include remote optical powering1 and remote optical switching.2,3 Pulses with peak power greater than 1 W and nanosecond duration are affected by stimulated Raman scattering (SRS). The high-energy pulses generate Stokes pulses by the process of amplified spontaneous Raman scattering4. This paper presents an experimental and theoretical study of the limitations imposed by SRS on pulses with peak power up to 60 W and duration on the order of 10 ns. Experiment shows and theory confirms that there is an optimum input power for a given pulse duration and distance that maximizes the energy transmitted over long fibers. To the best of our knowledge, this is the first demonstration of Stokes pulse generation from a pump pulse within the 1550 nm window.
