13.5 nm extreme ultraviolet emission from tin based laser produced plasma sources
P Hayden, A Cummings, N Murphy… - Journal of applied …, 2006 - pubs.aip.org
An examination of the influence of target composition and viewing angle on the extreme
ultraviolet spectra of laser produced plasmas formed from tin and tin doped planar targets is
reported. Spectra have been recorded in the 9–17 nm region from plasmas created by a 700
mJ, 15 ns full width at half maximum intensity, 1064 nm Nd: YAG laser pulse using an
absolutely calibrated 0.25 m grazing incidence vacuum spectrograph. The influence of
absorption by tin ions (Sn I–Sn X) in the plasma is clearly seen in the shape of the peak …
