Kapangidwe ka kristalo ka lithiamu tantalate (LiTaO₃, LT mwachidule) ndi ofanana ndi LN crystal, ya cubic crystal system, 3m point group, R3c mlengalenga gulu. LT crystal ili ndi piezoelectric, ferroelectric, pyroelectric, acousto-optic, electro-optic ndi nonlinear optical properties. LT crystal ilinso ndi mphamvu zokhazikika zakuthupi ndi zamankhwala, zosavuta kupeza kukula kwakukulu komanso kristalo wapamwamba kwambiri. Kuwonongeka kwake kwa laser ndikokwera kuposa LN crystal. Chifukwa chake crystal ya LT yakhala ikugwiritsidwa ntchito kwambiri pazida zam'mwamba zamayimbidwe.

 Makhiristo a LT omwe amagwiritsidwa ntchito kwambiri, monga makhiristo a LN, amakula mosavuta ndi ndondomeko ya Czochralski mu platinamu kapena iridium crucible pogwiritsa ntchito chiŵerengero cha lithiamu chopanda mphamvu cha co-composition yamadzimadzi. Mu 1964, crystal imodzi ya LT idapezedwa ndi Bell Laboratories, ndipo mu 2006, kristalo wa 5-inch LT adakulira ndi Ping Kang.ndi al.

 Pogwiritsira ntchito electro-optic Q-modulation, kristalo wa LT ndi wosiyana ndi LN crystal chifukwa chake γ₂₂ ndi yaying'ono kwambiri. Ngati itengera mawonekedwe a kuwala kodutsa motsatira optical axis ndi transverse modulation yomwe ili yofanana ndi LN crystal, mphamvu yake yogwiritsira ntchito imakhala yoposa 60 ya LN crystal pansi pa chikhalidwe chomwecho. Chifukwa chake, kristalo ya LT ikagwiritsidwa ntchito ngati electro-optic Q-modulation, imatha kutengera mawonekedwe a kristalo awiri ofanana ndi makristalo a RTP okhala ndi x-axis monga momwe amayendera komanso y-axis ngati njira yamagetsi, ndikugwiritsa ntchito mawonekedwe ake akulu amagetsi. kokwanira γ₃₃ ndi γ₁₃. Zofunika kwambiri pamtundu wa kuwala ndi makina a makristasi a LT zimachepetsa kugwiritsa ntchito electro-optic Q-modulation.
