(a, b) The spatiotemporal evolution of electron density with delay T_d = 6 fs and 12 fs, respectively. (c) Obtained radiation pulse intensity by applying a spectral filter to select the 30th to 100th harmonic orders at T_d = 6 fs. (d) Zoomed view of a single pulse with envelope fitting (red). The other simulation parameters are a = 10, τ = 6 T₀, L_s = 0.2 λ_L, n_e = 100 n_c, and normal incidence.
