We have demonstrated storage of 2 Kbits of data at 40 Mbits/s in the E
u3+ doped Y2SiO5 crystal using the time-domain echo approach. Preventi
ng coherent saturation, caused by the long data pulse train, is critic
al to the successful implementation of this technique. The experimenta
lly inferred storage capacity of 6 x 10(4) spatial spot demonstrates t
he potential of this optical memory.
