Simulation of Ni-like and Co-like X-rays emitted from laser produced tin plasmas

Abstract

The Ni-like and Co-like X-rays emitted from laser produced Tin plasmas generated using the 1.06 µm, 1.2 ns pulses from a Nd:YAG laser were modelled. The modelling includes the Ni-like and Co-like X-ray resonance line spectrum emitted from Sn plasma between 12 Å–25 Å and also free-free and free-bound continuous spectrum emitted from the Zn-, Cu-, Ni-, Co-and Fe-like ions between 1 Å and 30 Å. Then, X-ray conversion efficiencies were calculated using these spectra. Maximum X-ray conversion efficiency was obtained 3.54 % at power density of 5 × 10¹² W cm⁻² into 2π steradian. X-ray pulse durations were calculated spectrally integrated total X-ray emission of the Ni-like and Co-like from Sn plasmas.
