不同线型的擦除脉冲对存储光信息擦除的影响

Erasure of Stored Optical Information by Applying Erasing Pulses of Different Shapes

在Pr3+∶Y2SiO5(Pr∶YSO)晶体中,利用施加擦除脉冲破坏原子自旋相干,通过实验演示存储光信息的擦除操作,获得了85%的擦除效率,并分析了不同擦除脉冲对存储信息擦除的影响.

We experimentally demonstrate the erasure of stored optical information in a Pr^3＋ ： Y2SiO5 crystal by applying an erasing pulse to destroy atomic spin coherence. We observed an erasing efficiency of about 85% and discussed the erasure of stored optical information by applying different pulses.
