Abstract
The SHG coefficient of a proton-exchanged layer of LiNbO3, relative to the bulk value, has been measured for the first time by non-phase-matched SHG using a grating sample. It was found that the d33 coefficient is reduced to approximately 0.5 of the bulk value by proton exchanging in pure benzoic acid.Keywords
