Stark Width and Shift Measurements for the 696.543?nm ArI Line using Degenerate Four-Wave Mixing (DFWM) Spectroscopy

摘要: Sub-Doppler degenerate four-wave mixing (DFWM) spectroscopy in phase- conjugate configuration has been used to study Stark width and shift of the 696.543 nm ArI line a local thermal equilibrium argon arc plasma. DFWM for profile measurements as well plasma diagnostics. At high laser intensities, relationship between signal intensity temperature experimentally determined then In range low intensities measured approximated by third power Lorentzian with depending on intensity. The results diagnostics have compared those commonly optical emission spectroscopy. This comparison shows that methods give similar within uncertainty limits.
