[en] The time and space-integrated emission spectra measurements have been performed in plasma produced by 308 nm wavelength XeCl laser radiation (I_L=(4-10)·10¹² W/cm², τ=10 ns) and by 248 nm wavelength KrF laser pulse train radiation (I_L=5·10¹⁵ W/cm², τ=7 ps, 16 pulses in train) on CF_n 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
