摘　　要：Bi 12 TiO 20 (BTO)crystals have same structure as that of the Bi 12 SiO 20 (BSO)which is one of the most popular photorefractive materials.And both of them belong to cubic non centrosymmetric nonferroelectric materials.The cubic nonferroelectric oxides exhibit a number of advantages such as higher sensitivity and faster respond for applications in photorefractive.Compared to BSO,BTO have the largest electro optical coefficient and lower optical activity,especially it exhibits much high photosensitivity in the red light region that permits to use a cheap He Ne laser.It is,therefore,of high potential for applications in optical devices.Bi 12 TiO 20 (BTO)crystals have same structure as that of the Bi 12 SiO 20 (BSO)which is one of the most popular photorefractive materials.And both of them belong to cubic non centrosymmetric nonferroelectric materials.The cubic nonferroelectric oxides exhibit a number of advantages such as higher sensitivity and faster respond for applications in photorefractive.Compared to BSO,BTO have the largest electro optical coefficient and lower optical activity,especially it exhibits much high pho...
