Contribution

It demonstrates the significant role of photon correlations and pulse duration effects on stimulated emission in a waveguide-coupled atom system.

Findings

Photon correlation influences stimulated emission

Pulse duration affects atomic lifetime

Strong atom-photon interactions observed

Abstract

We study stimulated emission from an excited two-level atom coupled to a waveguide containing an incident single-photon pulse. We show that the strong photon correlation, as induced by the atom, plays a very important role in stimulated emission. Additionally, the temporal duration of the incident photon pulse is shown to have a marked effect on stimulated emission and atomic lifetime.
