• Li in-diffusion and out-diffusion processes in LiNbO_3 crystals, when treated in Li_2CO_3 powder, were investigated through second harmonic generation phase matching temperature measurement using a YAG laser. After annealing at 600℃ for more than 52 hours in Li_2CO_3, in-diffused Li ions caused a slight decrease in the ordinary refractive index near the surface of the polished LiNbO_3 substrate. These samples showed a large decrease in extraordinary refractive index after being annealed at l050℃ in air. Wrapping the LiNbO_3 substrate in platinum foil to prevent direct contact with the Li_2CO_3 powder was found to be a successful method to suppress Li out-diffusion without surface degradation.
