Light scattering from thermal density fluctuations using a CW-CO2-laser and heterodyne detection
Description
The ion feature in the scattered light spectrum of an arc plasma was measured using heterodyne detection. A low-power CW-CO2-laser was employed. The weak signals were discriminated against noise by lock-in technique. (orig.)

Mit Hilfe der Heterodyne-Nachweismethode wurde die Ionencharakteristik im Streulichspektrum eines Bogenplasmas gemessen. Dabei wurde ein CW-CO2-Laser geringer Leistung verwendet und die schwachen Signale durch Lock-in Methoden gegenueber dem Rauschen diskriminiert. (orig.)
