A long-lived multiple optical echo has been observed in a LaF3 :Pr3 + crystal (the 3H4 -3P0 transition). An agreement of the temporal shape of the signals representing the long-lived multiple optical echo and the temporal shape of the code pulse has been observed and studied for the first time under conditions of multiple readout.
