population transfer: dynamic Stark shifts and multiphoton ionization. We describe a
technique for overcoming these limitations by using a second field to control dynamic Stark
shifts via Stark-chirped rapid adiabatic passage (SCRAP) and simultaneously suppress
undesired photoionization via laser-induced continuum structure (LICS). We illustrate this
proposed procedure by numerical simulations of two-photon excitation of the metastable 2 s …
