Abstract
We present experimental results demonstrating 87% efficiency for single pulse recall, and storage of up to 20 pulses using a three level gradient echo memory with hot rubidium vapour as the storage medium. We also present results showing pulse resequencing, as well as pulse splitting and spectral manipulation. The decoherence mechanisms affecting the system, in particular scattering due to the control field and how it can be minimised by turning the control field off during storage, are also discussed.
