A Technique for Studying the Spectral Composition and Duration of Radiation Accompanying a Shock Wave at the Rear Surface of Materials under Direct Laser Irradiation

摘要

A photochronographic technique for studying the spectral composition and duration of radiation that accompanies the appearance of a shock wave on the rear surface of a loaded target has been developed. The spectral resolution of this technique was evaluated. A method of the through calibration of the recording channel using radiation of a source with the known spectrum was proposed. The results of the performed calibration are used to restore the spectral distribution on the basis of the obtained spectrochronograms.
