Abstract
The plasma produced by the interaction of a 1-ps, 1-rim, mid-1015 W/cm2 laser pulse with moderate Z targets is investigated spectroscopically using high-resolution, time-integrated x-ray and XUV spectrometers. The x-ray spectra are analyzed and the plasma conditions are inferred using a variety of theoretical models, including a time-dependent atomic physics computer code POPION. The electron temperature is estimated to be 1 keV during the transient plasma associated with the laser pulse. K emission may indicate the presence of a significant population of suprathermal electrons in the plasma.
