Low-intensity laser-electron scattering in the Thomson limit

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...

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...

Pulsed-laser nonlinear Thomson scattering for general scattering geometries.

In a recent paper it has been shown that single electron Thomson backscatter calculations can be performed including the effects of pulsed high intensity lasers. In this paper we present a more detailed treatment of the problem and present results for more general scattering geometries. In particular, we present new results for 90 degrees Thomson scattering. Such geometries have been increasing...

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...
