摘要：

We report on gain-saturated operation of the 4d -> 4p, J = 0-1, 11.4-nm soft-x-ray laser line in Ni-like antimony (Sb) at a pump energy of only 2.5 J. The driving laser used was a I 054-nm Nd:glass CPA laser system with a pulse duration of 7 ps (FWHM). The pump beam was focused with a tilted on-axis parabolic mirror in a grazing-incidence (GRIP) pumping configuration at an incidence angle of 45 degrees. A fraction of 2.8% of the pump energy (similar to 70mJ) was used for the prepulse, which was propagated along the same beam line as the main pulse and arrived at the target 4.4 us before the main pulse.
