LiNbO3 (Lithium Niobate) tioata o se mea lautele tele e tuʻufaʻatasia meatotino o piezoelectric, ferroelectric, pyroelectric, nonlinear, electro-optic, photoelastic, ma isi LiNbO3 e lelei le mautu vevela ma vailaau mautu.

O se tasi o mea sili ona lelei faʻailoaina nonlinear mea faitino, LiNbO3 e talafeagai mo le tele o taimi masani liua talosaga. Mo se faʻataʻitaʻiga, o loʻo faʻaaogaina lautele e avea ma faʻalua taimi mo le umi o le galu> 1 μm ma faʻataʻamilometi osilator uila (OPO) pamu i 1064 nm faʻapea foʻi ma quasi-phase-matched (QPM) masini. Ona o lona tele EO ma AO coefficients, LiNbO3 ua masani foi faaaoga tioata mo fase modators, waveguide substrate, luga acoustic galu wafers, ma Q-fesuiaiga o Nd: YAG, Nd: YLF ma Ti-Sapphire lasers.

LiNbO3 mafai ona doped ma le tele o elemene, pei Er, Pr, Mg, Fe, ma isi, lea e tuuina atu le mea mea ese meatotino. Mo se faʻataʻitaʻiga, o le mea e faʻaleagaina e MgO: LiNbO3 e sili atu faaluaina o le mama LiNbO3.

Faʻafesoʻotaʻi mai matou mo le mea sili mo lau talosaga o LiNbO3 alamanuia.
