Dimensionless diffusion coefficient in units versus energy in units for 0.035 (1), 0.05 (2), and 0.065 (3). Dashed curve, , corresponds to the short-range scattering case.
Normalized distribution of concentration and energy density (solid and dashed curves; ) versus dimensionless coordinate plotted for the time interval and different correlation lengths, (a) and 10 nm (b).
Spatio-temporal evolution of differential transmission coefficient for the mid-IR pumping case [energy density evolution is determined by Eq. (7)] at probe energies (a), 0.78 eV (b), and 0.6 eV (c).
Spatio-temporal evolution of differential transmission coefficient for the pumping in visible range (energy density evolution is shown in Fig. 2) at probe energies (a), 1 eV (b), and 0.8 eV (c).
