Isakhiwo sekristalu se-lithium tantalate (LiTaO₃, LT ngamafuphi) ifana nekristalu ye-LN, eyingxenye ye-cubic crystal system, 3m iqembu lamaphuzu, R3c iqembu lesikhala. Ikristalu ye-LT inezindawo ezinhle kakhulu ze-piezoelectric, i-ferroelectric, i-pyroelectric, i-acousto-optic, i-electro-optic kanye ne-nonlinear optical. Ikristalu ye-LT nayo inezindawo ezinzile ngokomzimba namakhemikhali, kulula ukuthola usayizi omkhulu kanye nekristalu eyodwa yekhwalithi ephezulu. Umkhawulo wokulimala kwe-laser uphakeme kune-LN crystal. Ngakho-ke ikristalu ye-LT isetshenziswe kabanzi kumadivayisi we-surface acoustic wave.

 Amakristalu e-LT asetshenziswa kakhulu, njengamakristalu e-LN, akhuliswa kalula ngenqubo ye-Czochralski ku-platinum noma i-iridium crucible kusetshenziswa isilinganiso esingenayo i-lithium sokuhlanganisa okuqinile koketshezi. Ngo-1964, ikristalu eyodwa ye-LT yatholwa yiBell Laboratories, kwathi ngo-2006, ikristalu eyi-5-inch LT yakhuliswa nguPing Kang.et al.

 Ekusetshenzisweni kwe-electro-optic Q-modulation, ikristalu ye-LT ihlukile kune-LN crystal ngokuthi i-γ yayo.₂₂ incane kakhulu. Uma yamukela imodi yokudlula kokukhanya eduze kwe-optical axis kanye nokushintshashintsha kwe-transverse okufana nekristalu ye-LN, i-voltage yayo yokusebenza ingaphezu kokuphindwe izikhathi ezingu-60 kune-LN crystal ngaphansi kwesimo esifanayo. Ngakho-ke, lapho ikristalu ye-LT isetshenziswa njenge-electro-optic Q-modulation, ingakwazi ukusebenzisa ukwakheka okufanayo kwekristalu okuphindwe kabili okufana nekristalu ye-RTP ene-x-eksisi njengesiqondisindlela sokukhanya kanye ne-y-eksisi njengesiqondisindlela senkundla kagesi, futhi isebenzisa i-electro-optic yayo enkulu. i-coefficient γ₃₃ kanye γ₁₃. Izidingo eziphezulu zekhwalithi yokubona nokwenza amakristalu e-LT zikhawulela ukusetshenziswa kwayo kwe-electro-optic Q-modulation.
