Technical tendency of electric field measurements in glow discharge plasmas using laser spectroscopy

레이저를 이용한 방전 플라즈마중의 전계측정 기술 동향

Direct measurements of electric fields in a glow discharge are difficult because the measurement method should be sensitive to the electric field and non-intrusive. Laser spectroscopy is very suitable in that it is non-intrusive and allow in-situ measurements to be made. In this report, the measurement techniques of electric fields in glow discharge using laser spectroscopy were described.
