Paper Abstract

We report on 2D near-field imaging experiments of the 11.9-nm Sn x-ray laser that were performed with a set of novel Mo/Y multilayer mirrors having reflectivities of up to 40% at normal and at 45° incidence. Second-moment analysis of the x-ray laser emission was used to determine values of the c-ray beam propagation factor M2 for a range of irradiation parameters. The results reveal a reduction of M2 with increasing prepulse intensity. The spatial size of the output is a factor of ~2 smaller than previously measured for the Pd x-ray laser, while the distance of the x-ray emission with respect to the target surface remains roughly the same.
