(a) and (b) The temporal and spectral profiles of output pulses with (blue solid lines) or without (red solid lines) considering plasma effect. Panels (c) and (f), (d) and (g), (e) and (h) represent the evolutions of peak intensity, time and frequency domains of the pulse with different fiber lengths, respectively. Panels (c)–(e) and (f)–(h) with or without plasma effect.
