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
