Description

The use of lasers as ultrasound sources is of interest in nondestructive materials testing, primarily because lasers provide a noncontact ultrasonic source. The generation and reception of ultrasonic waves has by now been widely demonstrated, as discussed in References 1, 2, and 3. Comprehensive numerical models are needed in order to quantify the waveforms generated by laser sources in the thermoelastic regime, and as an aid in designing nondestructive materials evaluation systems. Comprehensive models have been developed, for example by McDonald [4, 5], Schliechert et al. [6], and Spicer [7]. These numerical models have been experimentally confirmed by a number of researchers, including Schliechert et. al [6] and Spicer [7].
