Abstract

The electron velocity distribution function is the key parameter for understanding chemical kinetics in plasmas of discharge-pumped excimer lasers. Local and unambiguous determination of the parameter is presently only possible by the Thomson scattering, and this letter describes the first observation of the Thomson scattering signals from ruby laser light from an excimer laser. The results revealed otherwise inaccessible structure of the electron temperature, such as an increase of the temperature when the buffer gas was changed from helium to neon.
