The localized Coulomb dry friction on the surface of a rod significantly alters the propagation of an optodynamic wave. The effects of frictional clamping on the rod's dynamics were measured with a homodyne quadrature laser interferometer at the rear end of the rod. The measurements are supported by a theoretical description of the discrete motion of the finite rod, which is based on a general result representing the interaction of a laser-ablation-induced stress wave with a frictional clamping location.
