Paper Abstract

Optical homogeneity (birefringence and birefringence dispersion mapping, transmission and additional absorption) was investigated on the entire areas of LiNbO3 wafers doped with Cu ions and irradiated with protons of fluencies ranging between 1012 and 1016 cm-2. The birefringence dispersion studies have revealed a considerable influence of protons on LiNbO3:Cu optical inhomogeneity, whereas the same influence on undoped LiNb03 was much less significant. The spectroscopic studies have revealed different mechanisms of defect formation depending on doses of protons. Also the secondary electrons generated by proton irradiation are believed to decrease the optical homogeneity by decreasing crystal's conductivity and generation of the color centers.
