Lithium niobate (LiNbO3, nke akpọchiri dị ka LN) bụ kristal arụrụ arụ ọrụ yana ọtụtụ ebumnuche nke integrates magburu onwe electro-optic, acousto-optic, elastic-optic, piezoelectric, pyroelectric, photorefractive mmetụta na ndị ọzọ anụ ahụ Njirimara. kristal LN bụ nke sistemu kristal trigonal, yana usoro ferroelectric na ọnụ ụlọ okpomọkụ, 3m otu isi, na R3c otu oghere. N'afọ 1949, Matthias na Remeika haziri otu kristal LN, na 1965 Ballman tolitere nnukwu kristal LN.
In'afọ 1970 LN ca malitere iji rystals mee ihe na nkwadebe nke electro-optic Q-switch. kristal LN nwere uru nke enweghị deliquescent, obere voltaji ọkara ebili mmiri, mpụta mpụta, dị mfe ime electrodes, iji dị mma na mmezi, wdg, mana ha na-enwekarị mgbanwe mgbanwe fotorefractive ma nwee obere mmebi laser.

Iji dozie ihe nsogbu nke fotorefractive mmetụta, ọtụtụ ọrụs have e rụrụ. N'ihi na kristal LN a na-ejikarị eme ihebụ nke mepụtara eutectic ruru nke otu mejupụtara nke mmiri siri ike steeti, tebe a bụ ntụpọ dị ka ohere lithium na mgbochi niobium na kristal. Ọ dị mfe iji dozie ihe ndị kristal site n'ịgbanwe ihe mejupụtara na doping. N'afọ 1980,ya’s chọpụtara na kristal doping LN nwere ọdịnaya magnesium karịa 4.6 mol% na-abawanyes nke nguzogide mmebi foto site na ihe karịrị otu usoro nke ịdị ukwuu.
