Paper Abstract

Temporal and spatial electron density oscillation in laser wakefield was measured by Frequency-domain interferometry technique. The period of the plasma oscillation was measured to be 2 THz in the electron density of 5 X 1016 cm-3. In the measurement of radial profiles of electron density oscillation, the expulsion of electrons from the laser axis was apparently observed. These measurement techniques will enables us to perform a coherent control of electron plasma oscillation.
