| 英文摘要 | Raman scattering and photoinduced light scattering in co-, cr- and fe-doped lithium niobate were examined. the ai(to) modes appear in e symmetry spectrum of the doped lithium niobate. their intensities vary with different dopings. in the spectrum of z(yy)x geometry, the properties of the lowest-frequency e(to) mode of the cr-doped lithium niobate are different from those of pure, co-and fe-doped lithium niobate. the intensity of the a(1)(to) mode at 637cm(-1) is decreased in doped lithium niobate compared with the pure crystal. we attribute these properties to both the photorefractive effect which is enhanced by dopants and to the different occupation of the doping ions. a light climbing effect was observed in co- and cr-doped lithium niobate for the first time. a higher photodamage threshold and quicker light climbing speed were found in co- and cr-doped lithium niobate in comparison with the light climbing effect in the fe-doped lithium niobate. the results from the photoinduced light scattering experiments were compared with those from a raman spectroscopic study. |
