In-plane signal along $Q_z$ around the dynamical diffraction area between $0.6$ and $1.0 \mathrm{n}{\mathrm{m}}^{-1}$. (a) In-plane signal for different time delays at lower laser intensity case ($8\times {10}^{14} \mathrm{W}/\mathrm{c}{\mathrm{m}}^2$). (b) The circular dots display the integrated signal between $Q_z$ = 0.65–0.79 nm⁻¹ as a function of time delay. The dashed line represents a guide to the eyes. Blue color stands for the lower laser intensity of $8\times {10}^{14} \mathrm{W}/\mathrm{c}{\mathrm{m}}^2$ and red denote the higher laser intensity $8\times {10}^{15} \mathrm{W}/\mathrm{c}{\mathrm{m}}^2$.
