Cov qauv siv lead ua ntawm lithium tantalate (LiTaO₃, LT luv luv) zoo ib yam li LN siv lead ua, teej tug mus rau cubic crystal system, 3m pawg point, R3c pawg chaw. LT siv lead ua tau zoo heev piezoelectric, ferroelectric, pyroelectric, acousto-optic, electro-optic thiab nonlinear optical zog. LT siv lead ua kuj muaj lub cev ruaj khov thiab tshuaj lom neeg, yooj yim kom tau txais qhov loj me thiab zoo ib leeg siv lead ua. Nws qhov kev puas tsuaj laser yog siab dua li LN siv lead ua. Yog li LT siv lead ua tau siv dav hauv cov khoom siv acoustic yoj.

 Feem ntau siv LT crystals, zoo li LN crystals, yog yooj yim zus los ntawm Czochralski txheej txheem nyob rau hauv ib tug platinum los yog iridium crucible siv ib tug lithium-deficient ratio ntawm solid-kua co-composition. Xyoo 1964, Ib qho LT siv lead ua tau txais los ntawm Tswb Laboratories, thiab xyoo 2006, 5-nti LT siv lead ua tau loj hlob los ntawm Ping Kang.ua al.

 Nyob rau hauv daim ntawv thov ntawm electro-optic Q-modulation, LT siv lead ua txawv ntawm LN siv lead ua nyob rau hauv uas nws γ₂₂ me me heev. Yog tias nws siv cov qauv ntawm lub teeb hla dhau ntawm qhov chaw kho qhov muag thiab kev hloov pauv hloov pauv uas zoo ib yam li LN siv lead ua, nws qhov kev ua haujlwm voltage yog ntau dua 60 npaug ntawm LN siv lead ua nyob rau hauv tib yam. Yog li ntawd, thaum LT siv lead ua yog siv los ua electro-optic Q-modulation, nws tuaj yeem txais cov qauv siv lead ua ob npaug zoo ib yam li RTP siv lead ua nrog x-axis raws li lub teeb kev taw qhia thiab y-axis raws li hluav taws xob kev taw qhia, thiab siv nws loj electro-optic. coefficient γ₃₃ thiab γ₁₃. Cov kev xav tau siab ntawm kev kho qhov muag zoo thiab kev ua haujlwm ntawm LT crystals txwv nws daim ntawv thov ntawm electro-optic Q-modulation.
