Laser ultrasonics

Laser ultrasonics is a non-destructive testing (NDT) technique that utilizes laser technology to generate and detect ultrasonic waves in various materials. This method combines the principles of ultrasonics (which involves the use of high-frequency sound waves) with laser technology to analyze the properties and integrity of materials without causing any damage. ### Key Components of Laser Ultrasonics: 1. **Laser Generation**: A high-energy laser beam is focused onto the surface of the material being tested.
