Supersonic, counterstreaming plasmas were produced by ablating plasma from the inside surfaces of two parallel disks made of aluminum and magnesium, respectively, with a 0.53 μm laser at an intensity of 1014 W/cm2 for 1.3 nsec. Diagnostics included

An X-ray lasing oscillator is being developed which uses visible laser irradiation of solid targets in multipulse, multipass, operation to produce dramatic, rather than incremental, improvement in almost any X-ray lasing scheme. Hydrodynamic code sim

By means of two exploding foils, we have achieved inner-shell photoionization of Zn-like Pd resulting in the soft X-ray transition 3d 94s 2 → 3d 104p at 46 A.

Detailed atomic level populations in high temperature and dense plasmas have become increasingly important in laser generated plasmas. Certain spectral line intensity ratios are density-dependent while others are temperature-dependent. Both can be us

In the course of conducting laser–target interaction experiments at 20-ps pulse length using Al and Mg targets, to determine the ionization balance of these elements, time-resolved K-shell spectral line strengths were obtained, suggesting populatio

The x-ray spectrum emitted by a gas jet irradiated at ${10}^{16}$ W/${\mathrm{cm}}^{2}$ has been measured for laser wavelengths of 1.05 and 0.53 \ensuremath{\mu}m. The flux of hard x rays ($h\ensuremath{\nu}g~10$ keV) emitted by a gas jet is less tha

Volume compressions on the order of ${10}^{2}$ have been observed in glass microspheres heated by pulses from a Nd glass laser. The degree of compression is inferred from computer analysis of time-integrated x-ray photographs of the target plasma.

X‐ray spectroscopy was performed in the 12–15‐A region, recording L‐series lines from selected laser‐irradiated transition metals. Line coincidences and near coincidences were identified between Cr, Mn, Fe, and Ni L spectra, and F viii and
