Thomson scattering from laser plasmas

Laser Thomson Scattering Measurement to Diagnose the Low Temperature Plasmas

This paper describes how to measure the plasma temperature and density using laser Thomson scattering signal. Electron energy probability functions (EEPFs) having a fine resolution of electron energy were measured in low-pressure inductively coupled plasma with laser Thomson scattering method (LTS) at various plasma conditions (rf powers and gas pressures) and compared with the EEPFs measured b...

Laser Thomson Scattering Diagnostics of Dielectric Barrier Discharge Plasmas

Applications of Thomson scattering diagnostics to two kinds of dielectric barrier discharge (DBD) plasmas are presented. One is that for the plasma display panel. In order to avoid laser perturbations for Xe containing discharges which are easily disturbed by laser beams with visible wavelengths, a laser Thomson scattering (LTS) system having an infrared laser (wavelength 1064 nm) as a light so...

The Observation of Enhanced Thomson Scattering in Submicron-Laser Plasmas

Frequency up-scattered light produced by laser-plasma interaction was measured under three different plasma conditions. The corresponding down-scattered light was also observed. The measured wavelengths were, in all cases, in good agreement with the results of the enhanced Thomson scattcxing (ETS) theory. The upscattered band, shifted to a frequency higher than the laser frtquency wg, had not p...

Nonlinear Thomson scattering of intense laser pulses from beams and plasmas.

Corrections to Laser Electron Thomson Scattering

Thomson scattering is the classical process of light being deflected by a charged obstacle of typical size smaller than the wavelength of the incident radiation. For definiteness we will henceforth assume the charge to be an electron and the incoming wave stemming from a laser beam. The scattered radiation may be viewed as resulting from a two-step process: (i) the acceleration of the charge du...
