High-gain Er-doped fiber amplifier generating eye-safe MW peak-power, mJ-energy pulses.
We report on a large-core, Er-doped fiber amplifier that generates pulses of approximately 1.1 ns duration and maximum pulse energy/peak power approximately 1.4 mJ/1.2 MW, at 1567 nm wavelength, while concurrently providing optical gain in excess of 25 dB, in a multi-mode output beam (M(2) approximately 8.5).
