Generation of picosecond x-ray pulses in a dense plasma created by high-power femtosecond laser pulses of the 308 nm wavelength

A high-power femtosecond excimer XeCl laser system was used to generate radiation of over 10¹⁵ W/cm² intensity on the surface of a target. X-ray pulses were emitted by a laser-generated plasma. The duration of these pulses was less than 7 ps and the energy was in excess of 0.2 keV.
