A method for electric field measurement based on laser spectroscopy of argon atoms has been developed and calibrated. Measurements were made using both laser optogalvanic spectroscopy and laser-induced fluorescence spectroscopy. Measurements using se

The shape of absorption profiles obtained with single mode diode lasers in a cylindrical magnetron discharge are interpreted by properly taking into account longitudinal Zeeman-splitting and optical depth. Additional Doppler-free spectra were taken t

Width and shift of five prominent neutral neon spectral lines have been measured using a wall-stabilized arc. Under the prevailing plasma conditions the broadening by neutral disturbers has to be taken into account besides the Stark effect. This is a

The broadening and shift of the first two lines of the Paschen series of hydrogen have been investigated both experimentally and theoretically. The application of an earlier developed Green{close_quote}s-function approach predicts a nonlinear behavio

The radiative lifetime of the Kr III 5p 5P3 level has been measured by the technique of time-resolved laser-induced fluorescence and a novel ion source. In a first step doubly charged krypton ions are prepared by the combination of a pulsed electron

Polarization spectroscopy is used to determine shift and broadening coefficients for Stark and pressure effects of hydrogen Balmer- beta fine structure components in a low-density gas discharge. The beta lines are more sensitive to Stark broadening t

The theory of time-resolved laser-induced fluorescence (LIF) in a static magnetic field is reformulated by means of the graphical method of angular momentum theory. Invariant general geometrical relations of the time-resolved fluoresence signal are o

The Stark broadening tables for hydrogen Lyman, Balmer and Paschen lines published in the early seventies give accurate results for the widths of the β lines down to relatively low electron densities, and for the far line wings in general. However,
