- Abstract summary: We show that femtosecond extreme-ultraviolet pulses from a seeded free-electron laser can drive Rabi oscillations between the ground state and an excited state in helium atoms.
The measured photoemission signal revealed an Autler-Townes doublet as well as an avoided crossing.
Our results offer opportunities to carry out ultrafast manipulation of coherent processes at short wavelengths using free-electron lasers.

- Abstract: Rabi oscillations are periodic modulations of populations in two-level
systems interacting with a time-varying field. They are ubiquitous in physics
with applications in different areas such as photonics, nano-electronics,
electron microscopy, and quantum information. While the theory developed by
Rabi was intended for fermions in gyrating magnetic fields, Autler and Townes
realized that it could also be used to describe coherent light-matter
interaction within the rotating wave approximation\cite. Although intense
nanometer-wavelength light-sources have been available for more than a decade,
Rabi dynamics at such short wavelengths have not been observed directly. Here
we show that femtosecond extreme-ultraviolet pulses from a seeded free-electron
laser can drive Rabi oscillations between the ground state and an excited state
in helium atoms. The measured photoemission signal revealed an Autler-Townes
doublet as well as an avoided crossing, phenomena that are both trademarks of
quantum optics. Using theoretical analyses that go beyond the strong-field
approximation, we found that the ultrafast build-up of the doublet structure
follows from a quantum interference effect between resonant and non-resonant
photoionization pathways. Given the recent availability of intense attosecond
and few-femtosecond extreme-ultraviolet pulses, our results offer opportunities
to carry out ultrafast manipulation of coherent processes at short wavelengths
using free-electron lasers.
