Abstract
The FLASH XUV-free electron laser has been used to irradiate solid samples at intensities of the order 1016 W cm−2 at a wavelength of 13.5 nm. The subsequent time integrated XUV emission was observed with a grating spectrometer. The electron temperature inferred from plasma line ratios was in the range 5–8 eV with electron density in the range 1021–1022 cm−3. These results are consistent with the saturation of absorption through bleaching of the L-edge by intense photo-absorption reported in an earlier publication.
