Abstract

We report results of the study of warm plasmas generated by focusing 46.9 nm soft x-ray laser pulses of nanosecond duration onto Si, Cr and Ag targets. The absorption is dominated by single photon photoionization, resulting in plasmas that are significantly different from those created by visible lasers. Spectra from the soft x-ray laser-created plasmas agree with 1 ½ D simulations in showing that the Si plasmas are significantly colder and less ionized than the Cr and Ag plasmas, confirming that, in contrast to plasmas created by optical lasers, the plasma properties are largely dependent on the absorption coefficient of the target material.
