Ubume bekristale be-lithium tantalate (LiTaO3, LT ngokufutshane) iyafana nekristale ye-LN, eye-cubic crystal system, 3m iqela lamanqaku, R3c iqela lendawo. I-crystal ye-LT ine-piezoelectric egqwesileyo, i-ferroelectric, i-pyroelectric, i-acousto-optic, i-electro-optic kunye ne-nonlinear optical properties. Ikristale yeLT ineempawu ezizinzileyo zomzimba kunye neekhemikhali, kulula ukufumana ubungakanani obukhulu kunye nomgangatho ophezulu wekristale enye. Umda womonakalo we-laser uphezulu kune-LN crystal. Ke ikristale ye-LT isetyenziswe ngokubanzi kwizixhobo zamaza acoustic.
I-crystals ye-LT esetyenziswa ngokuqhelekileyo, njenge-crystals ye-LN, ikhula ngokulula ngenkqubo ye-Czochralski kwi-platinum okanye i-iridium crucible usebenzisa i-lithium-deficient ratio ye-solid-liquid co-composition. Kwi-1964, i-crystal ye-LT enye yafunyanwa yi-Bell Laboratories, kwaye kwi-2006, i-crystal ye-5-intshi ububanzi be-LT yakhuliswa nguPing Kang.okqhubekayo.
Ekusetyenzisweni kwe-electro-optic Q-modulation, ikristale yeLT yahlukile kwikristale ye-LN kuba i-γ yayo.22 incinci kakhulu. Ukuba yamkela imowudi yokudlula kokukhanya kunye ne-optical axis kunye nemodyuli eguquguqukayo efana nekristale ye-LN, amandla ombane osebenzayo angaphezulu kwamaxesha angama-60 ekristale ye-LN phantsi kwemeko efanayo. Ke ngoko, xa ikristale yeLT isetyenziswa njenge-electro-optic Q-modulation, inokwamkela ubume bekristale obuphindwe kabini obufana nekristale ye-RTP ene-x-axis njengesikhokelo sokukhanya kunye ne-y-axis njengesikhokelo sebala lombane, kwaye isebenzisa i-electro-optic yayo enkulu. ilingane γ33 kunye γ13. Iimfuno eziphezulu kumgangatho we-optical kunye nokulungiswa kweekristale ze-LT zinciphisa ukusetyenziswa kwayo kwe-electro-optic Q-modulation.
