(a) The relevant energy level diagram for Pr:YSO. (b) Pulse sequences of the three fields in the experiment.
Schematic diagram of the experimental setup. BS: beam splitter; : lens; AOM: acoustooptic modulator; PD: photodiode; and OS: oscilloscope.
Light storage and release demonstration. (a) and (c) demonstrate the pulse sequences before the crystal. (b) and (d) demonstrate the pulse sequences after the crystal.
(a) The relative amplitude of the restored pulse against time delay between the control pulse and signal pulse. The positive delay corresponds to the signal pulse being switched off last. Zero time delay corresponds to fractional STIRAP; delay corresponds to STIRAP. (b) The relative amplitude of the restored pulse against the storage time.
