Paper Abstract

Characteristics of a laser-generated acoustic source are discussed from measurements carried out using a Nd:YAG Q-switched laser incident on free metal surfaces. Longitudinal, shear and surface acoustic pulses have been generated. Laser energies as low as 3mJ are sufficient to generate such pulses that are readily detected by conventional piezoelectric transducers, without the need for laser focusing. Experimental data highlights several features of the acoustic source.
