Abstract
We have used the Shenguang II laser in third harmonic (351 nm) to investigate the emission of
L-shell radiation in the 3.3 to 4.4 keV range generated using thin foils of Sn coated onto a parylene
substrate with irradiation of order 1015 Wcm−2 and nanosecond pulse duration. In our experiment,
we have concentrated on assessing the emission on the non-laser irradiated side as this allows an
experimental geometry relevant to experiments on photo-ionised plasmas where a secondary target
must be placed close to the source, to achieve X-ray fluxes appropriate to astrophysical objects.
Overall L-shell conversion efficiencies are estimated to be of order 1%, with little dependence on
Sn thickness between 400 and 800 nm.
