Determining the Pseudo-Stark Coefficient in Y2SiO5:Er3+ from the Photon Echo Oscillations and Beats upon a 4F9/2–4I15/2 Transition

Аннотация

The pseudo-Stark shift in the optical frequency of the ⁴F_9/2–⁴I_15/2 transition of an Er³⁺ ion in a Y₂SiO₅ matrix under the action of a weak pulsed electric field is measured from changes in the amplitude and temporal shape of the photon echo.
