Conference Presentations:

Paper: 13342-3
Title: High-power, narrow-linewidth, reverse-pumped, Yb-doped fiber amplifier using novel 7+1:1 pump-signal combiner
Abstract: We report the performance of a high-power narrow-linewidth, reverse-pumped, Yb-doped fiber amplifier using a novel pump-signal combiner with seven, 230μm pump input pigtails, a 22/400 common pump/signal fiber, and 35/400 signal output fiber. Using this combiner in an amplifier we measured 3.7kW of output power at 11GHz linewidth with greater than 80% slope efficiency. Beam quality measurements showed diffraction limited output with M2=1.13.

Paper: 13342-14
Title: Polarization maintaining, low noise, 32W, 1280nm Raman amplifier
Abstract: We report an 8+1 to 1 pump-signal combiner (PSC) designed for backward pumping with higher-order mode content 19 dB lower than the fundamental mode in the output pigtail. The mode content is measured using the S2 measurement technique. The output beam M2 was near diffraction limited at M2 X of 1.23 and M2 Y of 1.21. The high signal beam quality is attributed to a high-quality taper and low overlap splice loss between the tapered fiber bundle and the output fiber. The combiner output fiber is large mode area with an LP01 mode field diameter of 33 µm at 1064 nm and mode effective area of 854 µm2. The large effective area of the output pigtail is ideal for low nonlinearity and high-power delivery. The additional pump ports allow for lower system weight by eliminating the additional layer of pump combiners (PC) in a PC+PSC tree of combiners and using higher power low brightness pump diode sources.

Paper: 13342-18
Title: Pulse-pumped, polarization maintaining, very-large-mode area erbium-doped fiber amplifier at low repetition rates
Abstract: We report a pulse energy of 1.73mJ at very low signal repetition rate of 150Hz from a single-frequency, 1534nm, polarization-maintaining amplifier using 2m long, very-large mode area erbium-doped fiber with 50μm core. The high output pulse energy was enabled by pulsing the pump lasers of the power amplifier and the final stage of the preamplifier. The FWHM of the output pulses was 1.27μs, and the peak power > 1.22kW. The output of the fiber power amplifier was diffraction-limited, with beam quality factor, M2, of 1.04. Stimulated Brillouin scattering limited the maximum energy.

Paper: 13342-39
Title: Single-frequency amplifier using polarization-maintaining Yb-doped 30/400 fiber
Abstract: We report the performance of a polarization-maintaining, 30/400 Yb-doped amplifier using a novel fiber with MFD of 26μm and increased higher-order mode suppression for high transverse-mode instability threshold. With a broad linewidth source, we obtain a TMI threshold of >2kW signal power in a fiber with 2.4dB/m pump absorption at 976nm. Polarization extinction ratio was >20dB and M2 was 1.1. Using a single frequency seed laser, we achieved 225W output power using an all-fiber fusion spliced system.
