Optical Parameter Effects on Laser Generated Ultrasound for Microstructure Characterization [link]Paper  abstract   bibtex   
Under appropriate conditions a significant feature of the laser generated elastic waveform in the thermoelastic regime is a precursor (sharp spike) signaling the arrival of the longitudinal wave. This paper shows that the observed precursor can be understood through the use of one-dimensional models that account for optical penetration and thermal diffusion into the material. Experimental results are compared with a two-dimensional analytic calculation including optical penetration.
