Abstract

Optical coherent transient experiments have proved especially useful in determining the homogeneous dephasing rates of rare earth impurity ions in solids and identifying the underlying relaxation mechanisms involved. We report on coherent transient studies on the 7F05D0 transition of Eu3+ in Eu3+:Y2O3, which differ from previous transient-type experiments in that the excitation pulses employed were of unequal bandwidth. It turns out that transients generated with pulses of greatly different bandwidth are sensitive to novel relaxation mechanisms and have allowed us to demonstrate quantitatively the presence of excitation- pulse-induced transition frequency shifts in the optical regime.
