- AlkaliAtom.getSaturationIntensityIsotropic(ng, lg, jg, fg, ne, le, je, fe)[source]#
Isotropic Saturation Intensity \(I_\mathrm{sat}\) for transition \(f_g\rightarrow f_e\) averaged over all polarisations in units of \(\mathrm{W}/\mathrm{m}^2\).
\(I_\mathrm{sat} = \frac{c\epsilon_0\Gamma^2\hbar^2}{4\vert \epsilon_q\cdot\mathrm{d}\vert^2}\)
- Parameters
ng – total orbital, fine basis (total atomic) angular momentum, and projection of total angular momentum for ground state
lg – total orbital, fine basis (total atomic) angular momentum, and projection of total angular momentum for ground state
jg – total orbital, fine basis (total atomic) angular momentum, and projection of total angular momentum for ground state
fg – total orbital, fine basis (total atomic) angular momentum, and projection of total angular momentum for ground state
mfg – total orbital, fine basis (total atomic) angular momentum, and projection of total angular momentum for ground state
ne – total orbital, fine basis (total atomic) angular momentum,
le – total orbital, fine basis (total atomic) angular momentum,
je – total orbital, fine basis (total atomic) angular momentum,
fe – total orbital, fine basis (total atomic) angular momentum,
mfe – total orbital, fine basis (total atomic) angular momentum,
