Abstract

Multiphoton resonances between dressed states of a doubly-driven two-level system $3\text{g}〉-\iff \widehat{U}3e〉-$ are observed by monitoring the absorption associated with a third level 3f〉−. The multiphoton resonances have been observed for the case where one field is resonant with the transition, and the detuning of the second field Δ₂ is given by -X₁ where X₁ is the Rabi frequency of the first field and n = 1,2,3.
