Bandwidth-induced reversal of asymmetry in optical-double-resonance amplitudes
Abstract
Optical-double-resonance measurements using ionization detection have been carried out in the 3S12-3P12-4D atomic-sodium system. Asymmetries observed in production of 4D atoms from the two components of the Stark-split 3P12 state are found to be controlled by the far, very weak wings of the 17-MHz full-width-at-half-maximum laser line which is used to drive the 3S12-3P12 transition at detunings in the range 0-70 GHz. Suppression of the wings with a Fabry-Perot filter causes a pronounced reversal of the asymmetry. © 1981 The American Physical Society.
