Abstract
In this paper, the ultrasonic displacement field in an anisotropic crystal generated by a pulsed laser line-source was precisely solved by the Cagniar d-de Hoop method. The experiment of measuring the ultrasound was carried ou t by the laser ultrasonic technique, which has unique features of non-conta ct, high spatial and temporal resolution. Our results obtained from a coppe r crystal (phi 35 X 15mm(3), the normal of the sample surface was along < 1 00 > direction) have shown the agreement between the theory and experiment.
