- Abstract
The instrumental complex described is intended for recording the velocity of motion of the surface of a sample under study exposed to impact-explosion loading in gas-dynamic investigations of properties of structural materials. The velocity is determined from the Doppler wavelength shift of reflected radiation of the probing laser measured by the interferometry method. A solid-state laser with a pulse duration of >50 μs, an average power of at least 50 W, and a system for controlling the resonator quality factor, which ensures radiation stabilization for maintaining an almost rectangular pulse shape, is used as the probing-radiation source.
