Abstract

The present state of Stark plasma spectroscopy is discussed. The possibilities of measurements of electric field and related plasma parameters are considered. A brief theory of linear and nonlinear Stark effect is outlined. The specific features of Stark effect — shifts, splitting and related line broadening, forbidden transitions — are described for the electric fields of differing nature — correlated external static and alternative fields, plasma turbulence fields, microfields generated by charged particles. Techniques based on classical emission spectroscopy, and novel linear and nonlinear laser techniques are considered. It is shown that the application of recently developed coherent laser spectroscopic methods radically improves the possibilities of electric fields measurements for the high pressure range.
