Abstract: 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. }}

Key words: light storage, light information erasure, Pr∶YSO crystal
