When optical frequency fields are used to couple a ground state to a
Rydberg state, the resonant dipole coupling is to a low angular momentum
state. Higher angular momentum states are typically thought not to play a
role in the excitation. The extremely large dipole matrix elements
coupling Rydberg states of the same n but differing l ,
however, allow optical fields of modest strengths to produce Rabi
frequencies larger than optical frequencies. We demonstrate that these
optical fields can therefore readily excite the higher angular momentum
states, and we examine the consequences of this coupling.
