Imiterere ya kristu ya lithium tantalate (LiTaO₃, LT muri make) isa na LN kristal, ya sisitemu ya cubic sisitemu, 3m itsinda ry'ingingo, R3c itsinda ryumwanya. LT kristal ifite piezoelectric nziza, ferroelectric, pyroelectric, acousto-optic, electro-optique na optique idafite optique. LT kristu nayo ifite imiterere ihamye yumubiri nubumashini, byoroshye kubona ubunini bunini hamwe nubuziranenge bwo hejuru. Ibyangiritse byangiritse birenze LN kristu. LT kristal rero yakoreshejwe cyane mubikoresho bya acoustic wave.

 Ikoreshwa rya kristu ya LT, nka LN ya kristu, ikura byoroshye na Czochralski muri platine cyangwa iridium ikomeye cyane ikoresheje igipimo cya Lithium-ibura-ya-ikomeye. Mu 1964, kristu imwe ya LT yabonywe na Bell Laboratories, naho mu 2006, umurima wa santimetero 5 ya LT yahinguwe na Ping Kangn'abandi.

 Mu ikoreshwa rya electro-optique Q-modulation, LT kristal itandukanye na LN kristu muburyo γ₂₂ ni gito cyane. Niba ifata uburyo bwurumuri rwambukiranya inzira ya optique na transvers modulasiyo isa na LN kristu, imbaraga zayo zikora zirenze inshuro 60 za LN kristu muburyo bumwe. Kubwibyo, iyo LT kristu ikoreshwa nka electro-optique Q-modulasiyo, irashobora gufata ibyuma bibiri bya kristu ihuza imiterere isa na RTP kristu hamwe na x-axis nkicyerekezo cyumucyo na y-axis nkicyerekezo cyumuriro w'amashanyarazi, kandi igakoresha amashanyarazi manini-optique coefficient γ₃₃ na γ₁₃. Ibisabwa cyane kurwego rwiza rwa optique no gutunganya kristu ya LT bigabanya ikoreshwa rya electro-optique Q-modulation.
