\label{Figure3}(A) \label{Figure4}(A)  Amplitude of the shear wave versus laser beam energy. Two power. A  linear dependences are dependence is  observed,a first between 10 and 70 mJ with a regression fit $y = 1.10^{-3}x$ (R$^2$ = 0.82), and a second one between 80 and 200 mJ  with a regression fit $y = 7.10^{-3}x -0.5$ (R$^2$ = 0.96). threshold at low amplitude due to ambient noise.  (B) Amplitude of the shear wave versus black disk diameter. A linear dependence is observed (R$^2$ = 0.9281). observed.
