LiNbO3 Subist
Fa'amatalaga
LiNbO3 Crystal ei ai mea fa'apitoa fa'aeletise-optical, piezoelectric, photoelastic ma nonlinear optical properties.Latou te malosi birefringent.O loʻo faʻaaogaina i le faʻaluaina o le laserfrequency, optics nonlinear, pockels cell, oscillators parametric optical, Q-sui masini mo lasers, isi masini acousto-optic, sui opitika mo ala gigahertz, ma isi. O se mea sili ona lelei mo le gaosiga o taʻiala faʻafefete, ma isi.

LiNbO3 Substrate Fa'amatalaga:
LiNbO3 (lithium niobate) substrate e faasino i se mea tioata e masani ona faʻaaogaina e fai ma mea faʻapipiʻi poʻo se mea faʻapipiʻi i masini eletise ma optoelectronic eseese.O nisi nei o manatu autu e uiga i LiNbO3 substrates:
1. Faʻailoga tioata: LiNbO3 o se tioata ferroelectric faʻatasi ai ma se fausaga perovskite.E aofia ai le lithium (Li) ma le niobium (Nb) atoms o loʻo faʻatulagaina i totonu o se lattice tioata faapitoa.
2. Piezoelectric meatotino: LiNbO3 o loʻo i ai le malosi o le piezoelectric, o lona uiga e faʻatupuina le eletise pe a oʻo i le mamafa o masini ma le isi itu.O lenei mea totino e talafeagai mo faʻaoga e pei o masini acoustic waves, sensors, actuators, etc.
3. Mea tau eletise: LiNbO3 o loʻo iai foʻi mea sili ona lelei ma faʻaogaina eletise.O lo'o i ai se fa'ailoga maualuga, maualalo le malamalama, ma fa'aalia se mea e ta'ua o le electro-optic effect, lea e mafai ai ona suia lona fa'ailoga e ala i se malae eletise fafo.O nei meatotino e fa'aoga ai i fa'aoga e pei o masini fa'apipi'i, ta'iala galu, fa'alua fa'atele, ma isi mea.
4. Tele lautele o le manino: LiNbO3 o loʻo i ai le tele o faʻamatalaga manino, faʻatagaina e tuʻuina atu le malamalama i le vaʻaia ma latalata-infrared fusi.E mafai ona fa'aogaina e fau ai masini fa'apitoa o lo'o fa'agaoioia i nei vaega o le galu.
5. Fa'atupula'ia ma fa'atonuga: LiNbO3 tioata e mafai ona fa'atupuina i le fa'aogaina o metotia eseese e pei o le Czochralski ma le fa'ato'a fa'atupuina o vaifofo pito i luga.E mafai ona tipi ma fa'asinotonu i fa'atonuga tioata eseese ina ia maua ai mea fa'apitoa ma eletise e mana'omia mo le gaosiga o masini.
6. Maualuluga faʻainisinia ma vailaʻau: LiNbO3 e faʻainisinia ma faʻamalosi kemisi, e mafai ai ona tumau.
