| Outline of Final Research Achievements |
Conventional methods of high sensitivity electric field measurement in plasmas are Stark spectroscopy with a high power tunable laser. In this work, we applied saturation spectroscopy, which is high resolution Doppler-free spectroscopy, to Stark spectroscopy in plasmas with a tunable diode laser. Direct detection of Stark effect in sheath region is achieved for atomic hydrogen Balmer-alpha line with absorption sensitivity enhancement method.
