摘要

Raman spectra of LiNbO_(3) crystals with different hydrogen-ion-exchanged time were examined.E(TO)and A1(TO)modes appear gradually in the transverse A1-and E-symmetry spectra respectively with increasing the exchange time and the dependence of their intensities on the exchange time is also observed.We attribute these results to both the internal strains resulting from the ordering-disordering distribution of H ions in the sample and the enhanced photorefractive effect.
