Abstract
Peak power in single frequency fiber amplifiers is limited by stimulated Brillouin scattering (SBS) particularly for optical pulses with several hundreds of nanoseconds duration. The SBS threshold can be increased by scaling the fundamental mode effective area while taking care to maintain the beam quality. To increase the peak power of amplifiers beyond the fiber SBS threshold, we chose a strain-based SBS mitigation technique [1].
