Spectral diagnostic of a resonantly laser created plasma
Published online by Cambridge University Press: 09 March 2009
Abstract
Plasma creation occurs when the frequency of a tunable dye laser is adjusted to the 589 nm D-doublet of the sodium atom. Occurrence and Stark broadening of emission lines in the fluorescence light are used as diagnostics. The time history of the electron density and temperature is inferred from these measurements. The peak electron density was found to be above 5 · 1016 cm−3 with a temperature lower than 1 eV.
