Poyerekeza ndiwabwino LNkristalo(CLN)ndi mapangidwe omwewo, kusowa kwa lithiamu pafupi-stoichiometricLNkristalo(SLN)kumabweretsa kuchepa kwakukulu kwa zolakwika za lattice, ndipo katundu wambiri amasintha molingana.Pansipa pali mndandanda waukulukusiyana kwakatundu wakuthupi.
Kuyerekeza kwa Properties pakati pa CLN ndi SLN
| Katundu | Mtengo wa CLN | SLN |
| Birefringence / 633nm | -0.0837 | -0.0974 (Li2O=49.74mol%) |
| EO coefficient /pm•V-1 | r61= 6.07 | r61=9.89 (Li2O=49.95mol%) |
| Nonlinear coefficient /pm•V-1 | d33=19.5 | d33=23.8 |
| Photorefractive saturation | 1×10-5 | 10×10-5 (Li2O=49.8mol%) |
| Photorefractive yankho nthawi /s | mazana | ～0.6 (Li2O=49.8mol%, Iron-doped) |
| Photorefractive resistance / kW•cm-2 | 100 | 104 (Li2O=49.5-48.2mol%, 1.8mol% MgO doped) |
| Domain flip electric field intensity /kV•mm-1 | 21 | 5 (Li2O=49.8mol%) |
Poyerekeza ndiMtengo wa CLNndi kapangidwe chomwecho, zambiri katundu waSLNzakonzedwa mosiyanasiyana.Kukhathamiritsa kofunikira kwambiri kumaphatikizapo:
(1) Whether photorefractive doping, anti-photorefractive doping kapena laser-activated ion doping,SLN nditcheru kwambiri ntchito malamulo zotsatira.Kong et al.anapeza kuti pamene [Li]/[Nb] ifika ku 0.995 ndipo magnesium ili ndi 1.0mol%, kukana kwa photorefractiveSLNimatha kufika 26 MW/cm2, yomwe ili madongosolo 6 apamwamba kuposa aMtengo wa CLNndi zolemba zomwezo.Photorefractive doping ndi laser-activated ion doping imakhalanso ndi zotsatira zofanana.
(2) Monga kuchuluka kwa zilema za lattice muSLNkristalo imachepa kwambiri, momwemonso mphamvu yamagetsi ya kristalo imachepa, ndipo mphamvu yamagetsi yofunikira kuti polarization isinthe imachepa kuchokera pafupifupi 21 kV/mm.(wa CLN)mpaka pafupifupi 5 kV/mm, zomwe zimapindulitsa kwambiri pokonzekera zida za superlattice.Komanso, dongosolo lamagetsi lamagetsi laSLNndizokhazikika komanso makoma a domain ndi osalala.
(3)Ma photoelectric ambirikatundu waSLNZimakhalanso bwino kwambiri, monga electro-optic coefficientr61chawonjezeka ndi 63%, coefficient nonlinear chinawonjezeka ndi 22%, crystal birefringence chinawonjezeka ndi 43% (wavelength 632.8 nm), kusintha kwa buluuwa UVm'mphepete mwa mayamwidwe, etc.
