Iyo crystal chimiro che lithium tantalate (LiTaO₃, LT for short) yakafanana neLN crystal, ye cubic crystal system, 3m point group, R3c space group. LT crystal ine yakanakisa piezoelectric, ferroelectric, pyroelectric, acousto-optic, electro-optic uye nonlinear optical properties. LT crystal zvakare ine yakagadzikana yemuviri uye makemikari zvivakwa, zviri nyore kuwana hukuru hukuru uye yakakwirira mhando yekristaro imwechete. Yayo laser kukuvara chikumbaridzo chakakwira kupfuura LN crystal. Saka LT crystal yakashandiswa zvakanyanya mupamusoro acoustic wave zvishandiso.

 Makristasi eLT anowanzo shandiswa, seLN crystals, anokura nyore nyore neCzochralski process mu platinum kana iridium crucible achishandisa lithium-deficient ratio of solid-liquid co-composition. Muna 1964, A single LT crystal yakawanikwa neBell Laboratories, uye muna 2006, 5-inch dhayamita LT crystal yakakurira naPing Kang.et al.

 Mukushandiswa kweelectro-optic Q-modulation, LT crystal yakasiyana neLN crystal pakuti γ yayo.₂₂ idiki kwazvo. Kana ikatora modhi yechiedza ichipfuura ichitevedza optical axis uye transverse modulation iyo yakafanana nekristaro yeLN, voltage yayo inoshanda inodarika ka60 iyo yeLN crystal iri pasi pemamiriro akafanana. Naizvozvo, kana kristaro yeLT ichishandiswa se electro-optic Q-modulation, inogona kutora iyo yakapetwa kaviri kristaro inoenderana chimiro chakafanana neRTP crystal ine x-axis sechiedza chegwara uye y-axis semagetsi emumunda, uye kushandisa hombe yayo yemagetsi emagetsi. coefficient γ₃₃ uye γ₁₃. Izvo zvinodikanwa zvakanyanya pamhando yemaziso uye machining eLT makristasi zvinomisa kushandiswa kwayo kwe electro-optic Q-modulation.
