- Abstract: We investigated the Autler-Townes splitting produced by microwave transitions
between atomic Rydberg states explored by optical spectroscopy from the ground
electronic state. The laser-atom Hamiltonian describing the double irradiation
of such a multilevel system is analysed on the basis of the Morris-Shore
transformation. The application of this transformation to the microwave-dressed
atomic system allows the identification of bright, dark, and spectator states
associated with different configurations of atomic states and microwave
polarisation. We derived synthetic spectra that show the main features of
Rydberg spectroscopy. Complex Autler-Townes spectra are obtained in a regime of
strong microwave dressing, where a hybridisation of the Rydberg fine structure
states is produced by the driving.
