Doppler-free two-photon polarization spectroscopy was used for measuring the Stark-broadening of the 2S-level (Lyman-α transition) of hydrogen in an arc plasma at electron densities around ; 10 21 ; m -3; in order to examine corresponding theories. This electron density range, not accessible so...
In the last few years a new field, atomic physics and spectroscopy with non-classical, squeezed light, has emerged. The frequency tunable sources of such light utilize tunable lasers and frequency doubling and/or parametric down conversion to create quantum correlations between frequency...
A model based on an extension of the Frequency Fluctuation Model (FFM) is developed to investigate the two-photon processes and particularly the radiative redistribution functions for complex emitters in a wide range of plasmas conditions. The FFM, originally, designed as a fast and reliable...
