The second-order optical nonlinearities for fresnoite-type crystals were investigated. The study was carried out by the measurements on transparent surface-crystallized glasses consisting of Ba2TiSiO2 (BTS), Sr2TiSiO2O8 (STS) and Ba 2TiGe2O8 (BTG) by Maker fringe technique. It was found that the BTG has large d33 value, comparable to LiNbO 3 single crystal. The results show that the d33 value of fresnoite-type crystals increases with increasing c/a ratio in the lattice parameters of their structure.
