Optical Detection of Ultrasound using Two-Wave Mixing in Semiconductor Photorefractive Crystals and n be used to probe parts at elevated temperature, in particular on a production line, and parts of complex shape. However, optical techniques are typically less sensitive than conventional piezoelectric-based techniques.. Hence, efforts have been done to improve the sensitivity of optical techniques

High Frequency Laser-Ultrasonicsons involving attenuation measurements in weakly attenuating materials, or velocity measurement in thin samples or coatings may require a much higher detection bandwidth. By shortening the generation light pulse and improving the interferometer electronics, laser-ultrasonic bandwidths of 500 MHz wer
