TL;DR
This paper demonstrates that the AC-Stark shift can be used to effectively control photon-echo emission in optical storage, enabling modulation of echo efficiency through light-shift control pulses in erbium-doped solids.
Contribution
It introduces a novel method of controlling photon-echo emission using light-shift induced spatial gradients, advancing optical storage techniques.
Findings
Photon-echo efficiency can be fully modulated by light-shift control pulses.
Light-shift control induces a spatial gradient that influences echo emission.

Abstract
We show that the AC-Stark shift (light-shift) is a powerful and versatile tool to control the emission of a photon-echo in the context of optical storage. As a proof-of-principle, we demonstrate that the photon-echo efficiency can be fully modulated by applying light-shift control pulses in an erbium doped solid. The control of the echo emission is attributed to the spatial gradient induced by the light-shift beam.
