AlkaliAtom.getDrivingPower(n1: int, l1: int, j1: float, mj1: float, n2: int, l2: int, j2: float, mj2: float, q: int, rabiFrequency: float, laserWaist: float, s: float = 0.5) → float[source]#

Returns a laser power 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)

  • rabiFrequency – laser power in units of rad/s

  • 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:

laserPower in units of W

Return type:

float
