Kuphatikiza pa piezoelectric effect, mphamvu ya photoelectric yaLNkristalo ndi wolemera kwambiri, pakati pawo mphamvu ya electro-optical ndi nonlinear optical effect imakhala ndi ntchito yabwino kwambiri ndipo imagwiritsidwa ntchito kwambiri.Komanso,LNkristalo akhoza kukhalaamakonda kukonzani mawonekedwe apamwamba kwambiri opangira ma waveguide posinthanitsa ndi proton kapena kufalikira kwa titaniyamu, ndinawonsoakhoza kukhalaamakonda kukonzani polarization crystal polarization reversal. Chifukwa chake, LN crystal ili ndi ntchito zambiri in E-Omodulator (monga momwe zikuwonekera pachithunzichi), gawo modulator, chosinthira chophatikizira cha kuwala,E-O Q-kusintha, E-Oma deflectors, masensa apamwamba kwambiri, kuzindikira kutsogolo kwa mafunde, ma oscillator owoneka bwino ndi ma ferroelectric superlatticesndi zina..Kuphatikiza apo,ntchito za LN crystal-basedmphesa ziwiriangle plates, holographic optical devices, infrared pyroelectric detectors ndi erbium-doped waveguide lasers zanenedwanso.

Mosiyana ndi ntchito za piezoelectric, ase mapulogalamu okhudza kufala kwa kuwala kumafuna zosiyanantchitozaLNmakhiristo.Firstly, ndikufalikira kwa mafunde a kuwala, ndikutalika kwa mafunde kuchokera mazana a nanometers kupita ku ma microns ochepa, amafuna kristalo osati kutiali ndi mawonekedwe owoneka bwino kwambirikomanso kukhala mosamalitsa controllable azolakwika za kristalondi kukulakufanana ndi mphepokutalika.Chachiwiri,it nthawi zambiri ndizofunikirazaoptical kugwiritsa ntchito kuwongolera magawo ndi magawo a polarization a mafunde a kuwala omwe akufalikira mu kristalo.Izi zikugwirizana mwachindunji ndi kukula ndi kugawa kwa refractive index ya kristalo, kotero ndikofunikira kuthetsa mukupsinjika kwamkati ndi kunjawa kristalo momwe ndingathere. LNmakhiristo omwe amakwaniritsa zofunikira za optical application nthawi zambiri amatchedwa "optical gradeLNkristalo”.

X-axisLNkristalo amagwiritsidwa ntchito makamaka pokonzekera X-cut LNchowotcha, kuti zigwirizane ndi kudula, chamfering, akupera, kupukuta, photoliography ndi zina wotsatira umisiri processing opangidwa ndi ndondomeko semiconductor.X-axisLNkristalo ndimakamakaamagwiritsidwa ntchito kwambiriEOmodulators, gawo modulators, birefringent wedge magawo, waveguide lasers ndi zina zotero.
