Paper Abstract

We report on gain-saturated operation of the 11.9-nm x-ray lasing line in Ni-like Sn using the grazing-incidence pumping scheme (GRIP). The experiments were done with 2-ps duration pump pulses and energies up to 5 J. Strong gain saturation with ⪆10-microJ output was measured for the Sn laser at a grazing angle of 45° and a pump pulse energy of 5 J. This was achieved with a 4.5%, 2-ps duration prepulse 1.6 ns ahead of the main pulse and also incident at grazing incidence. Increasing laser output was observed at GRIP angles from 22.5° to 45°. At this angle, the minimum energy required for saturated lasing was determined as ~2 J.
