X-ray diagnostics for investigation of nanosecond laser plasma

In this paper, the object of study is a laser plasma produced by nanosecond (~ 2.2 ns) laser low coherence radiation interacted with different solid targets. In the irradiation of target by a laser pulse with intensity of ~ 1012 – 1014 W/cm2, the temperature of the formed plasma can be up to a few keV, and the maximum emissivity falls on the X-ray spectrum region. Developed X-ray diagnostics complex allows one to study of luminosity distribution of plasmas with high spatial, spectral and temporal resolution.
