WebIn order to achieve atom trap lifetimes greater than 10 s, far-off resonant trap (FORT) depths on the order of milli-Kelvin are required. Unfortunately, FORTs operating in this regime also induce excited state AC stark shifts that compromise laser cooling and coherent control of the optical transitions.
