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