Changes in carrier population for the normal incidence. a Spectrum cuts of Δf(E), inferred from the second integral Eq. (4), at t = 70, 150, 250, 500 fs. The relatively broad initial electron energy distribution change at the earlier time (70 fs) evolves to a narrower and larger magnitude Fermi–Dirac distribution at later time (500 fs). b Same as a but with multiplication factors in order to better compare the various time functional forms
