Investigation of Diagnostic Methods of Electron Number Density in Laser Plasma

Abstract:

Langmuir probe, interferometry/reflectometry and optical emission spectroscopy, diagnostic methods in common use for plasma, were analyzed. Basic principles, system compositions and applicable range were compared with each other. Optical emission spectroscopy method is easy to obtain temporal and spatial information and has large measuring range, which is more suitable for diagnosis for laser plasma.
