OpticalPotential

class OpticalPotential(atom, laser, name, options)

Bases: Potential, matlab.mixin.Heterogeneous

OpticalPotential is an abstract potential generated by light fields.

Couples a Laser to an Atom to compute recoil quantities and scalar polarizability for ground states (D-lines) via ScalarPolarizabilityGround. Concrete subclasses include OpticalTrap and OpticalLattice.

Example:

trap = OpticalTrap(atom, gaussianBeam);
Er = trap.RecoilEnergy;
