Measurements in Plasma Diagnositics Using a Mach-Zehnder Interferometer

Abstract

In the paper the principle of the optical interference method is described and formulas for determining the value of the interference fringes shift are derived. Dispersion equations stating the relation between the refractive index N and the gas density P, the given free electrons concentration, and the product of the concentration of excited atoms in the state I and the respective strength of the given oscillator are presented. A Mach-Zehnder interferometer is the most frequently used apparatus for the interference measurements of these quantities. The interferometer with a crossed spectrograph using white light according to Rozhdyestvenskiy is described.
