摘要：

Direct measurements of the diffusion distance of E»(E2) state excitation by time-resolved degenerate four-wave mixing in ruby are reported. Measurements are made on crystals with Cr3+ concentrations varying between 0.05 and 1.55 at.% at 10°K. In all cases an upper limit of 30 nm is determined for the diffusion distance within the fluorescence lifetime. © 1979 The American Physical Society.
