Shear wave amplitude has been shown to be linearly dependent on laser beam power in thermoelastic and ablative regime, until plasma occurs at very high power (about 10$^9$ W.cm$^{-2}$ in metals) \cite{scruby1990laser}. The dependence of the generated shear waves on laser energy was then investigated by increasing the laser beam energy from 0.5 to 10 mJ.mm$^{-2}$. Results are illustrated in Figure \ref{Figure4}-(A). We observe an linear relationship between shear wave amplitude and laser beam power, with a correlation coefficient of 0.9386. At an energy smaller than 50 mJ, shear wave amplitude becomes however smaller than ambient noise. Due to this linear dependency, the plasma regime can be discarded.
