Generation of sub-100 fs pulses tunable from 1.8 to 2.0 μm from an All-fiber, All-PM Source Pumped at 1560 nm

摘要

We report an all-fiber, all-polarization maintaining (PM) source of widely tunable (1800 - 2000 nm) ultrashort pulses based on amplification of frequency-shifted solitons generated in a highly nonlinear fiber. The system delivers sub-100 fs pulses with energies exceeding 8 nJ and is built entirely from polarization maintaining optical fibers, without any free-space optics.
