概要
- 論文の詳細を見る
Laser-induced fluorescence spectra were measured on the H_α and H_β lines in a thermal plasma produced by a high power microwave radiation. Saturation behavior of the fluorescence was made clear for both lines. Special attention was paid to the check of power broadening using two dye lasers with different spectral bandwidths. It was demonstrated again that the broadening was an important phenomenon in a high density plasma under study and we could estimate the Stark width of the line emission having Voigt or almost Doppler profiles without de-convolution technique. By this active spectroscopy it was also possible to decide the electron density in agreement with the one obtained from the emission spectroscopy.
