Abstract :
Summary from only given. We demonstrate that bend loss-induced mode filtering is effective in scaling large-core-area fiber amplifiers to significantly higher pulse energies and peak powers while maintaining diffraction-limited beam quality, high repetition rates, and transform-limited temporal and spectral profiles. This system provides the highest single-transverse-mode pulse energy, peak power, and average power simultaneously extracted from a fiber amplifier to date.
