A stimulated photon-echo study has verified the instantaneous shift (1 MHz) and subsequent restoration (2 ms) of the transition frequency of an impurity ion in a solid when its neighboring ions are exposed to pulsed optical excitation. Experiments were conducted by monitoring the echo intensity for the 7F0-5D0 transition of Eu ions in one site of Y2SiO5, while exciting the other site. A photon-echo theory taking account of the stochastic frequency recovery is developed to explain the observations.
