Abstract

When a 2-level atom is irradiated by a quasi-resonant light bean, having a frequency ωL close to the atomic frequency ωO, its energy levels a and b are shifted. Perturbation theory shows that the so called light-shift t εa of the lower level a (which is equal to −εa) is proportional to the light-intensity I and inversely proportional to the detuning ωL–ωO, provided that this detuning is not too small.

  25. The reabsorption of the fluorescence light in the cell is more important on the 2p10 to 1s4 transition than on the 2p10 to 1s3 one. We have been therefore obliged to reduce the Neon pressure to 0.3 Torr, which explains why the signal to noise ratio is lower than on Fig.5

  26. When the Zeeman structure exists in the lower level a (scheme of Fig.6) calculations similar to the ones of sect’on 4 lead to a slightly different compensation condition 262/(w1’ + 262) = s.
