All-in-fiber amplification and compression of coherent frequency-shifted solitons tunable in the 1800–2000 nm range
Abstract
We report an all-fiber, all-polarization maintaining (PM) source of widely tunable (1800–2000 nm) ultrashort pulses based on the amplification of coherent self-frequency-shifted solitons generated in a highly nonlinear fiber pumped with an Er-doped fiber laser. The system delivers sub-100 fs pulses with energies up to 8.6 nJ and is built entirely from PM optical fibers, without any free-space optics. The all-fiber alignment-free design significantly increases the suitability of such a source for field deployments.
