摘要：We present spectral hole-burning measurements of the 4 I 9/2 → 4 F 3/2 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.
