- Аннотация: The dependence of the visible spectrum (harmonics 2 and 3/2) and the output of CuKα-alpha X-ray radiation on the energy and duration of subrelativistic intensity femtosecond laser pulse acting on a copper foil is investigated. It was found that for secondary radiation, the determining factor is the energy density, and not the intensity and duration of the pulse. The power-law dependencies of the secondary output radiation on the duration and the pulseenergy have a significantly different indicator. The tendencies of changing the shape of the spectrum for regions dominated by various mechanisms of plasma heating are revealed.
