Abstract
Pulses of longitudinal, shear and surface waves are generated when a powerful laser pulse interacts with a surface of a solid. These waves serve to control strength, structure, and dynamic modulus of elasticity of solids. They are also used for ultrasonic testing.The optical methods and means have been developed in Dalstandart, RSRI of PTM, for generation and reception of ultrasonic waves in the frequency range of 0-30 MHz. Efficient techniques have been devised to determine different parameters of ultrasonic wave propagation, such as propagation velocities, coefficients of sound attenuation, and acoustic dispersion. Based on theoretical and experimental background the devised installations offer the highest accuracy for measurement of parameters of ultrasonic wave propagation in solids.
