The resulting displacement amplitude maps alongY axis and  Z axis 0.8, 1.6, 2.4, 3.2 1.0, 1.5, 2.0, 2.5  and 4.0 3.0  ms after laser emission in the phantom are illustrated in Figure \ref{Figure2}. \ref{Figure2}, for two laser beam energies (10 and 200 mJ).  A typical shear wave pattern can be recognized:antisymmetry for the Y-displacement,  symmetry for the Z-displacement \cite{undefined}. The displacement reached an amplitude of 3 $\mu$m. 0.01 $\mu$m for the 10 mJ laser beam and 2 $\mu$m for the 200 mJ.  The displacement propagated at a velocity of 4.5$\pm$0.5 5.5$\pm$0.5  m.s$^{-1}$, which is a typical value for shear wave, and far lower than usual compression wave velocity, about 1500 m.s$^{-1}$ in soft tissues. Supposing the medium density $\rho$ of 1000 kg.m$^{-3}$, it corresponds to a shear modulus of 20 30  kPa, which is in range of the expected value of the phantom. Shear wave frequency was equal to 500 $\pm$ 50 Hz.
