arc.alkali_atom_functions.AlkaliAtom.getSaturationIntensity#

AlkaliAtom.getSaturationIntensity(ng, lg, jg, fg, mfg, ne, le, je, fe, mfe, s=0.5)[source]#

Saturation Intensity \(I_\mathrm{sat}\) for transition \(\vert j_g,f_g,m_{f_g}\rangle\rightarrow\vert j_e,f_e,m_{f_e}\rangle\) 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,

  • state (and projection of total angular momentum for excited) –

  • s (float) – optional, total spin angular momentum of state. By default 0.5 for Alkali atoms.
