(color online) Pumped by input pulses with pulse durations of (a), (c) 200 fs and (b), (d) 1000 fs, peak power of 15560 W, and center wavelength of 2870 nm. The blue and green curves in panels (a) and (b) show the LWE and the PPL beyond 3 μm, respectively. (c), (d) The SD of spectrum density with 20 dB bandwidth versus propagation distance in the As2S3 SCF with a ZDW of 2825 nm.
