In summary, this study presented observation of elastic shear waves generated in soft tissues using a laser beam. The involved phenomenon was investigated. Experiments in chicken breast sample showed the feasibility of the elastography method using a laser beam as a shear wave source.  The authors would like to thank Damien Garcia for lending the laser device. Pol Grasland-Mongrain received a FRM SPE20140129460 post-doctoral grant. The authors declare no conflict of interest in the work presented here.ERASE ME !
