Columns represent: (1) α - absorption coefficient; (2) d - film thickness; (3) λ - wavelength used in the photorefractive experiments; (4) Γ - two-beam coupling (TBC) gain coefficient; τg-1 - response speed obtained from fits to TBC dynamics; ηmax - maximal diffraction efficiency (internal or external, as indicated) measured in the four-wave-mixing (FWM) experiment; τFWM-1 - speed of photorefractive grating formation or erasure measured in the FWM experiment; Δn - refractive index modulation calculated from the diffration efficiency.
