ʻO ke ʻano aniani o ka lithium tantalate (LiTaO₃, LT no ka pōkole) like ia me LN crystal, nona ka ʻōnaehana kristal cubic, 3m hui kiko, R3c hui ākea. Loaʻa i ka kristal LT ka piezoelectric maikaʻi loa, ferroelectric, pyroelectric, acousto-optic, electro-optic a me nā waiwai optical nonlinear. Loaʻa ka LT crystal i nā waiwai kino a me nā kemika, maʻalahi ke loaʻa ka nui nui a me ke aniani kiʻekiʻe kiʻekiʻe. ʻOi aku ka kiʻekiʻe o kona paepae pōʻino laser ma mua o ke aniani LN. No laila ua hoʻohana nui ʻia ka kristal LT i nā mea hawewe acoustic surface.

 ʻO nā kristal LT maʻamau i hoʻohana ʻia, e like me nā kristal LN, ua maʻalahi ke ulu ʻia e ka kaʻina Czochralski i loko o ka platinum a iridium crucible me ka hoʻohana ʻana i ka lakio lithium-deficient o ka hui pū ʻana me ka wai. I ka makahiki 1964, ua loaʻa i kahi aniani LT hoʻokahi e Bell Laboratories, a i ka makahiki 2006, ua ulu ʻia kahi aniani 5-inihi LT e Ping Kang.et al.

 I ka hoʻohana ʻana i ka electro-optic Q-modulation, ʻokoʻa ka kristal LT mai ka kristal LN i kona γ.₂₂ he uuku loa. Inā hoʻohana ʻo ia i ke ʻano o ka māmā e hele ana ma ka axis optical a me ka transverse modulation e like me ka kristal LN, ʻoi aku ka nui o kāna voli hana ma mua o 60 mau manawa o ka kristal LN ma lalo o ke ʻano like. No laila, ke hoʻohana ʻia ʻo LT crystal e like me ka electro-optic Q-modulation, hiki iā ia ke hoʻohana i ka ʻano like ʻole o ke aniani ʻelua e like me ka RTP crystal me ka x-axis ma ke ʻano māmā a me ka axis y e like me ke kuhikuhi kahua uila, a me ka hoʻohana ʻana i kāna electro-optic nui. koena γ₃₃ a me γ₁₃. ʻO nā koi kiʻekiʻe e pili ana i ka maikaʻi optical a me ka machining o nā kristal LT e kaupalena i kāna noi ʻana o ka electro-optic Q-modulation.
