AlkaliAtom.getRabiFrequency(n1, l1, j1, mj1, n2, l2, j2, q, laserPower, laserWaist, s=0.5)[source]#

Returns a Rabi frequency for resonantly driven atom in a center of TEM00 mode of a driving field

Parameters

  • n1 – state from which we are driving transition

  • l1 – state from which we are driving transition

  • j1 – state from which we are driving transition

  • mj1 – state from which we are driving transition

  • n2 – state to which we are driving transition

  • l2 – state to which we are driving transition

  • j2 – state to which we are driving transition

  • q – laser polarization (-1,0,1 correspond to \(\sigma^-\), \(\pi\) and \(\sigma^+\) respectively)

  • laserPower – laser power in units of W

  • laserWaist – laser \(1/e^2\) waist (radius) in units of m

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

Returns

Frequency in rad \(^{-1}\). If you want frequency in Hz, divide by returned value by \(2\pi\)

Return type

float
