On the calculation of laser-generated ultrasound pulses
The generation of ultrasound pulses with pulsed lasers has received considerable attention in recent years. Promising applications are to nondestructive evaluation and to materials characterization, where it is convenient to have a broad-band source requiring no contact with the sample. Quantitative...

Summary: | The generation of ultrasound pulses with pulsed lasers has received considerable attention in recent years. Promising applications are to nondestructive evaluation and to materials characterization, where it is convenient to have a broad-band source requiring no contact with the sample. Quantitative applications in nondestructive evaluation require theoretical calculations incorporating realistic sample and source properties. We will describe and illustrate a very recent formulation which enables such calculations to be accomplished more easily. Numerical results will be presented to demonstrate the advantages of this approach, with emphasis on the effects of finite source dimensions, and on the initial waveform. We also show that this approach may be used to investigate surface-wave generation. |
