| Abstract: | Li-rich vapor transportation equilibration(VTE) effects on the surface refractive index of congruent MgO∶LiNbO3 crystals were investigated.The results showed that the influence of VTE on the surface ordinary index no was remarkable in both the variation tendency against VTE duration and the amplitude changes of the index.The surface extraordinary index ne showed VTE effects similar to that of no but with smaller amplitude. |
