Research Abstract

For applying a future nuclear fusion reactor, Terahertz time domain spectroscopy system, which a femto-second fiber laser is used as a pumped laser and a photo-conductive antenna is uses as a emitter, has been developed. The key factors which are a long distance transmission, a high time resolution, etc. are studied to get the technical characteristics for a future system design. Also, the analytical method to apply the plasma diagnostics has been obtained.
