Simulations with (a) the measured spectrums and (b) the PICASO-reconstructed pulses output from the grating prechirper (black solid curve) and the SMF (red solid curve) as the input signal. Amplified pulse evolutions along the fiber under a pump wavelength of 976 nm (blue solid curve) and 915 nm (green solid curve): (c) the misfit parameter and (d) the pulse peak power.
