Space 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 کاملSpace-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 کاملXUV diagnostics of colliding laser-produced magnesium plasmas
Charge exchange collisions between highly charged Mg ions in colliding laserproduced magnesium plasmas are studied. Pinhole photography and XUV spectroscopy are used as diagnostic tools. XUV pinhole pictures taken at early stages give more insight into the expansion dynamics of the colliding magnesium plasmas. Spectroscopic studies show selective population of the n = 3 levels of Mg IX ions whi...
متن کاملCharge-exchange collisions in interpenetrating laser-produced magnesium plasmas
Charge-exchange collisions are one of the effective pumping methods for soft X-ray lasers. Experiments are performed to investigate charge-exchange collisions between highly charged Mg ions in colliding laser-produced magnesium plasmas. Pinhole photography and XUV spectroscopy are used as diagnostic tools. Spectroscopic studies show selective population of n 5 3 levels of Mg IX ions, which resu...
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...
