Directional Characteristics of a Laser Pulsed Thermoacoustic Emitter in Nonmagnetic Metals

Resumo

Results of experiments on studying the dependence of the directivity of a pulsed laser thermoacoustic emitter of longitudinal and transverse ultrasonic waves that operates in a nonmagnetic conducting medium on the surface density of laser-radiation heat power are presented. The results can be recommended for nondestructive testing of nonmagnetic materials and articles with laser ultrasonic sources.
