Shift 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-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 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...
متن کاملShort-pulse laser-produced plasmas
In this review, the physics of short-pulse laser-produced plasmas at moderate intensities is described, together with applications to x-ray sources and material processing.
متن کاملEvolution analysis of EUV radiation from laser-produced tin plasmas based on a radiation hydrodynamics model
One of fundamental aims of extreme ultraviolet (EUV) lithography is to maximize brightness or conversion efficiency of laser energy to radiation at specific wavelengths from laser produced plasmas (LPPs) of specific elements for matching to available multilayer optical systems. Tin LPPs have been chosen for operation at a wavelength of 13.5 nm. For an investigation of EUV radiation of laser-pro...
