This study presents the first observation of elastic shear waves generated in soft tissues using a laser beam. In a first set of experiments, we show that a 532 nm, 200 mJ laser beam can induce a displacement shear wave  in a soft phantom and that this displacement shear wave  was detectable by an ultrasound scanner using speckle-tracking algorithms. In a second set of experiments, we show that shear waves can be induced by a laser beam in a chicken breast sample. The results shows the feasability of an elastography method using a laser beam as a shear wave source.
