Experimental and theoretical study of acoustic waves generated by a laser line pulse in an optically absorptive isotropic cylinder
The cylindrical problem geometry.
Acoustic response at the surface of the NG5 glass rod: the experimentally recorded signal (top curve), the calculation taking into account the effect of optical penetration of laser energy (middle curve), and the calculation based on the surface-source model (bottom curve). The wave-arrival notations are explained in the text.
Directivity patterns of radiation of longitudinal wave by (a) the volume-distributed source and (b) the surface dipole source into the half-space consisting of NG5 glass material.
