Figure 2
(a) Real and (b) imaginary component of lithium polarizability over a range of light detuning and for a few light intensities, I. Polarizability is calculated using the resonance wavelength of the \(D_2\) line of \({}^6\)Li, \(\lambda _0=670.977\) nm and spontaneous emission rate, \(\gamma _N=5.9\times 10^{6}\) Hz. Note that \(\alpha _{\mathrm{ref}}=2.704\times 10^{-39}\) F\(\mathrm{m}^2\).
