Generation of Ultrasound by Laser

Various physical processes may take place when a solid surface is illuminated by a laser, some of which generate ultrasound. At lower incident powers these include heating, the generation of thermal waves, elastic waves (ultrasound), and in materials such as semiconductors, electric currents may be caused to flow. At higher powers, material may be ablated from the surface, and a plasma formed, while in the sample there may be melting, plastic deformation and even cracks formed.
