Abstract: (5283 Views)
The ultrasound waves can be generated by incidence of a short laser pulse on the specimen surface in thermoelastic and ablation regimes. In this paper, we have simulated ultrasonic wave forms in these regimes. Then we have generated these waves experimentally and we have compared these results with these simulations. The effect of two parameters, laser power density and pulse energy, on ultrasonic waveforms was analyzed. Comparing the experimental and simulated results indicates that the power density could change the ultrasonic wave generation regime. On the other hand, the laser pulse energy could increase the ultrasound wave amplitude regardless of its regime
