TL;DR
This paper investigates phase-dependent interference effects in multi-photon atomic excitation using bichromatic radio-frequency fields, demonstrating how interference patterns reveal the carrier-envelope phase even with long pulses.
Contribution
It provides both experimental and theoretical insights into phase-dependent interference in multi-photon atomic excitation, specifically in the Zeeman sub-levels of rubidium-87.
Findings
Interference effects depend on the phase difference between fields.
The method allows determination of the carrier-envelope phase.
Experimental results agree with theoretical predictions.
Abstract
We present an experimental and theoretical study of phase-dependent interference effects in multi-photon excitation under bichromatic radio-frequency (rf) field. Using an intense rf pulse, we study the interference between the three-photon and one-photon transition between the Zeeman sub-levels of the ground state of Rb that allows us to determine the carrier-envelope phase of the fields even for long pulses.
