Efficient spectral hole-burning and atomic frequency comb storage in Nd3+:YLiF4

摘要

We present spectral hole-burning measurements of the ⁴I9/2 → ⁴F3/2 transition in Nd³⁺:YLiF4. The isotope shifts of Nd³⁺ can be directly resolved in the optical absorption spectrum. We report atomic frequency comb storage with an echo efficiency of up to 35% and a memory bandwidth of 60 MHz in this material. The interesting properties show the potential of this material for use in both quantum and classical information processing.
