Displacements can again be computed by convoluting the applied force 4-D matrix $H_z^{abla}(y,z,t)$ with $G_{zz}$.  Using same values for the physical quantities as previously, results are illustrated in Figure \ref{figGreen}-(B) which represents displacement maps along Z axis, 1.0, 1.5, 2.0, 2.5 and 3.0 ms after force application. The displacement maps present many similarities with the experimental results of the Figure \ref{Figure2}: \ref{figElastoPVA}-(B), with  initial displacement is directed inside the medium and only two half cycles are propagating. Ablation regime has also confirmed visually: at high power, a disk of paler color of the same size as the beam diameter appears at the impact location of the laser on the phantom, which is consistent with the theory of a partial vaporization of the medium. This was not observed in the low-energy experiments.
