    "abstract": "We demonstrate photon echoes in Eu$^{3+}$:Y$_{2}$SiO$_{5}$ by controlling the\ninhomogeneous broadening of the Eu$^{3+}$\n$^{7}$F$_{0}\\leftrightarrow^{5}$D$_{0}$ optical transition. This transition has\na linear Stark shift and we induce inhomogeneous broadening by applying an\nexternal electric field gradient. After optical excitation, reversing the\npolarity of the field rephases the ensemble, resulting in a photon echo. This\nis the first demonstration of such a photon echo and its application as a\nquantum memory is discussed.",
