Electric Dipole Moment | Magnesium Atom

[robmichaels]

Firstly, I apologise if this is in the wrong place as it's not a homework question as such, but it is part of coursework.

I am modelling the trapping and cooling of an atom with a laser, and have an equation for the dipole moment which I think may be off. I am getting strange results (slowing down atoms from 100m/s to 0 in 10^30 seconds), and I'm fairly sure the rest of the data input is correct

Relevant equations
I have for my equation:
{mu}=((3*{Pi}*{hbar}*{epsilon₀}*c^3)/{omega₀}^3)^1/2

If this is the right equation, can someone explain to me what omega₀ represents and roughly to what power it should be for a magnesium atom.

Omega0 is the angular frequency of the laser, and it should be given in rad/s. For a magnesium atom, the angular frequency should be around 4.88 x 10^14 rad/s.
