TIME RESOLVED MEASUREMENTS OF ELECTRON NUMBER DENSITY AND ELECTRON TEMPERATURE USING LASER INTERFEROMETRY AT 337hyphen;mgr;m WAVELENGTH

摘要

An experiment is described where a cw HCN laser working primarily at 337hyphen;mgr;m wavelength was used as the source of a Machhyphen;Zehnder interferometer for the study of plasma decay in the electron number density region 5 middot; 1015ne 5 middot; 1013cmminus;3. It was found that an estimate of the electron temperature in the range 103minus;104deg;K could also be made from the amplitude of the interferometer fringes.
