Laser Ultrasound

  • Profile and Objective

    Laser Ultrasound is a modern non-destructive method for material testing. Especially it is suited for the investigation of solid surfaces. In our laboratory, we use this method to determine the elastic properties of thin films. In the framework of an international cooperation, we investigate new physical effects in connection with the propagation of guided acoustic waves.
