Abstract
The theoretical community has found interest in the ability of a two-level
atom to generate a strong many-body interaction with light under pulsed
excitation. Single-photon generation is the most well-known effect, where a
short Gaussian laser pulse is converted into a Lorentzian single-photon
wavepacket. However, recent proposals have surprisingly suggested that
scattering with intense laser fields off a two-level atom may generate
oscillations in two-photon emission that are out of phase with its Rabi
oscillations, as the power of the pulse increases. Here, we provide an
intuitive explanation for these oscillations using a quantum trajectory
approach and show how they may preferentially result in emission of two-photon
pulses. Experimentally, we observe signatures of these oscillations by
measuring the bunching of photon pulses scattered off a two-level quantum
system. Our theory and measurements provide crucial insight into the
re-excitation process that plagues on-demand single-photon sources while
suggesting the production of novel multi-photon states.
