Space-dependent shift of spectral lines in laser-produced plasmas
2014 A space-dependent red-shift of extreme ultraviolet lines of aluminium laser-plasma is observed on a distance covering more than 100, in a single-shot experiment. For radiation coming from highest density plasma, the shift can exceed the broadening of the lines. In the first approximation, this shift does not depend on plasma optical thickness. Various aspects of Stark effect are discussed ...
متن کاملShift of K-lines in Laser Produced Dense Plasmas
In order to develop X-ray probes for Compton scattering on warm dense plasmas K-lines have been investigated by irradiation of solid targets with intense ultra-short pulsed lasers, e. g. spectroscopy of chlorine Kα (2p→ 1s) and Kβ (3p→ 1s) was performed at Europa Laser Facility LLNL. Measurements of the characteristic X-ray emission show that average line positions shift as function of laser en...
متن کاملSpace Resolved Study of Laser Produced Plasmas
The study of plasma accelerated ions is an important topic nowadays [1]. The acceleration of ions is produced for electric fields caused by plasma density gradients. So a diagnostic of the plasma density and temperature is necessary. It is frequently achieved using spectroscopic methods with the light from He-like and Li-like plasma ion transitions emitted in the soft x-ray region, 1-1000 Å wav...
متن کاملSpectral analysis of the acoustic emission of laser-produced plasmas.
A Q-switched frequency Nd:YAG laser was focused on copper, aluminum, and lead targets. The acoustic emission accompanying plasma formation was acquired and analyzed in both the time and the frequency domains. Spectral analysis of the shock wave has proved to be a simple and low-cost diagnostic of plasma phenomena. In the time domain, several propagation mechanisms of the shock wave were observe...
متن کاملDiagnostics of laser-produced plasmas
Laser-produced plasmas are used for a variety of studies, relevant for both basic physics and applications, and are of course essential within the study of inertial confi nement approach to nuclear fusion. Because of this large interest, a large variety of diagnostics have been developed and are routinely used to unveil the physical processes at work during plasma process and laser-plasma inter...
