Abstract
The soft-x-ray and XUV emission from laser-produced plasmas produced by 300-mJ pulses from 1.06- and 10.6-μm lasers was compared both by measuring the absorption due to inner-shell photoionization in Cd vapor in the 10–71-nm region and by directly observing the plasma emission in the 35–75-nm region. The results indicate that a 10.6-μm laser can be a more efficient pumping source for a photoionization laser than a 1.06-μm laser in the nanosecond pulse regime at low laser intensities.
