Contribution

It provides an analytical and numerical study of bright-state STIRAP, including pulse reshaping effects and conditions for near-complete population transfer over long distances.

Findings

Identifies pulse parameters for efficient long-distance transfer

Analyzes limitations of adiabaticity in pulse propagation

Describes pulse reshaping effects on population transfer

Abstract

We describe analytically and numerically the process of population transfer by stimulated Raman adiabatic passage through a bright state when the pulses propagate in a medium. Limitations of the adiabaticity are analyzed and interpreted in terms of reshaping of the pulses. We find parameters for the pulses for which the population transfer is nearly complete over long distances.
