Resonant Ionization Schemes R&D

Resonant laser excitation and ionization schemes can be classified into schemes that (i) use a non-resonant ionization step, and (ii) ones that resonantly excite into either a high lying atomic Rydberg- state, or into an auto-ionizing state. The latter process in general yields by far the highest ionization efficiencies.
