摘要：

Sample dependent optical dephasing is observed for the F-7(0) double-line arrow pointing left and right 5D0 transition of Eu3+ in Y2O3 crystals prepared by flame fusion, are imaging and laser heated pedestal growth techniques. Two pulse photon echo measurements at show that the homogeneous line widths vary over nearly two orders of magnitude in the different samples (GAMMA(H) = 42 kHz), and are uncorrelated with the Eu3+ concentration. The temperature dependence of GAMMA(H) is nearLy linear in temperature (1-12 K), similar to that observed for disordered systems. The measured line widths may be associate limited disorder in the crystalline state. We also report on the line width of optical holes burned in the F-7(0) double-line arrow pointing left and right 5D0 transition of a MOCVD Y2O3 film containing approximately 2 at.% Eu3+. We find GAMMA(H) = 12 MHz at 1.4 K, about 10(3) times than that measured in the bulk crystals, and it is also linearly dependent on temperature.
