Abstract

Using Stark-pulse-modulated photon echoes, we observe a novel type of rephasing phenomenon in a ${\mathrm{Eu}}^{3+}$- and ${\mathrm{Pr}}^{3+}$-codoped Y₂SiO₅ crystal. By adjusting the Stark pulse during the rephasing and dephasing periods one can observe a full recovery of the photon echo, corresponding to perfect dephasing–rephasing balancing of the perturbations. We propose to use this effect as a spectroscopic technique to distinguish between reversible and irreversible Stark interactions.
