Recent results and future plans for XRLs using the TARANIS laser facility
The results of an investigation into X-ray lasing in Ni-like Sm, pumped by a frequency doubled pre-pulse and a fundamental short pulse, are presented. Strong lasing was observed across the 4d3/2-4p3/2 transition at 7.3 nm. A weaker laser line of wavelength 6.9 nm was also present from the 4d3/2-4p1/2 transition. The XRL output was seen to be sensitive to both delay between the pre-pulse and the heating pulse and also to the energy in the heating pulse. The results are compared to those from a similar experiment employing pre-pulses at the fundamental wavelength and the output of the XRL is shown to be enhanced by at least two orders of magnitude for the same target lengths. An application for an XRL pumped by Taranis is discussed.
