A Study of the Laser Generated Ultrasonic in Metal

    Graphical Abstract
    • Abstract
  • Ultrasonic pulse are generated by irradiation with a Q-switched Nd: YAG laser. The effects of the laser power density and the conditions of the metal surface on the intensity of the ultrasonic pulse are studied. The effects of a simulated defect in the metal sample on the propagation of the ultrasonic pulse are also studied.
