Laser-Aided Plasma Diagnostics
Fusion Science and Technology, 2004This paper will focus on two types of laser-aided diagnostics: Thomson scattering and laser-induced fluorescence. Thomson scattering is a very powerful diagnostic, which is applied at nearly every magnetic confinement device. Depending on the experimental conditions different plasma parameters can be diagnosed.

Abstract A review of high density, high temperature plasma production with pulse lasers is presented. In view of possible applications to thermonuclear fusion we limit our discussion to plasma generation from solid targets of low atomic number Z, with particular emphasis on solid deuterium.

A mathematical model of proton image formation is developed, and minimum size of objects visible under proton irradiation (resolution of proton radiography) is estimated. Due to ion flux being laminar, micron-sized objects smaller than the ion emission spot size are detected. The results of simulation are in good agreement with the experiment.

Abstract When the output of a typical Q-switched laser is focused onto a solid target, a short-lived, localized plasma, characterized by very high ion and electron densities and by very high temperatures, is formed. The present article begins with an outline of the essential features of the laser systems used to generate such plasmas followed by a ...

Laser beam-plasma coupling in laser solenoid plasmas
The Physics of Fluids, 1976A model has been constructed to analyze the gross beam-plasma interaction in a laser solenoid plasma. The model includes a simple solution for a slab plasma response to a given laser beam, and a solution for axial beam size variations in response to arbitrary axial plasma structure.

Diamond-like films containing no hydrogen can be deposited from laser plasmas that are highly ionized. Growth rates of 0.5 μm/h over 100 cm2 areas have been realized on untreated substrates of a variety of materials including Si, Ge, ZnS, glass, and plastics. Measurements of optical properties and mass densities support the identification of this laser

In the aftermath of a plasma in atmospheric density H2 produced by a 6 ns, 600 mJ, 1064 nm, Nd:YAG laser pulse, a bubble develops behind the shock front. Within 2 micros the shock detaches from it, but the bubble persists for 100 micros before it is clearly turbulent.

The calculations of the multiparticle dynamics that stimulate the important stages of relaxation of an ultracold laser plasma (N{sub e} {approx}2x10{sup 9} cm{sup -3}, T{sub e} {approx}0.1 K, T{sub i} {approx}10 {mu}K) are presented. The initial electron heating, the formation of highly excited electrons, and the confinement of electrons in a small ...
