The reflectivity (a) and reflected lateral shifts (b) for negative chirped laser field versus different incident angles by increasing the intensity of laser field from \(\Omega \) to \(2\Omega \) for \({\Gamma }_{12}^{-1}={\Gamma }_{34}^{-1}=1.7 \mathrm{ps}, {\Gamma }_{13}^{-1}={\Gamma }_{14}^{-1}={\Gamma }_{23}^{-1}={\Gamma }_{24}^{-1}=100 \,\mathrm{fs}, {\gamma }_{ij}^{-1}=1 \,\mathrm{ns}, \tau =17 \,\mathrm{fs}\), and \({\varphi }^{"}={-10}^{3}{fs}^{2}\).
