Calculations of Stark-broadened line shapes in phase-conjugate degenerate four-wave mixing laser spectroscopy.

摘要: The Stark-broadened line shapes for phase-conjugate degenerate four-wave mixing (PCDFWM) laser spectroscopy are studied. profiles calculated high-density $({N}_{e}g{10}^{21}\phantom{\rule{0.3em}{0ex}}{\mathrm{m}}^{\ensuremath{-}3})$ plasma conditions and different contributions of the Doppler broadening. Calculations performed in limit low intensities using perturbation approach. theoretical model takes into account Stark effect together with ion dynamics, electron collisions, effect. resultant PCDFWM spectral significantly less broadened asymmetric than emission but shifted by similar magnitudes. Moreover, results our calculations show sub-Doppler character also their strong dependence on geometric configuration pump probe beams.
