X-ray spectral line shapes for the excimer-laser-produced high density plasma diagnostics

The time and space-integrated emission spectra measurements have been performed in plasma produced by 308 nm wavelength XeCl laser radiation (IL=(4−10)⋅1012 W/cm2, τ=10 ns) and by 248 nm wavelength KrF laser pulse train radiation IL=5⋅1015 W/cm2, τ=7 ps, 16 pulses in train) on (CFn plane target. The lines' shapes and intensities modeling of Lyman series and He-like ion resonance series of fluorine up to n=7 by fitting experimental data shows the considerable difference of plasma formation features for these two sets of the laser pulse parameters.
