Abstract

Laser experiments of the plasma jet formation using nanosecond laser pulses with low energy, i.e., <20J, are presented. Planar and cratered gadolinium and aluminum targets are irradiated with laser intensities of several 1014W/cm2. Spatially-resolved time-integrated X-ray spectra were recorded in the spectral range from 7 to 10Å. A jet-like structure is obtained from aluminum targets with a preformed crater, which is not seen in planar target irradiation. For gadolinium, a jet is observed from both planar and preformed cratered targets, suggesting that the collimation is dominated by radiative cooling. A radiation-hydrodynamics code coupled to a non-LTE ionization code was used to model the plasma. The calculated plasma emission was found to be consistent with the experimental results.
