Ugereranije nabisanzwe LNkristu(CLN)hamwe nibintu bimwe, kubura lithium hafi-stoichiometricLNkristu(SLN)biganisha ku kugabanuka gukomeye inenge ya lattice, kandi imitungo myinshi ihinduka ukurikije.Imbonerahamwe ikurikira irerekana ibyingenziitandukaniro ryaimiterere yumubiri.
Kugereranya Ibyiza hagati ya CLN na SLN
| Umutungo | CLN | SLN |
| Birefringence / 633nm | -0.0837 | -0.0974 (Li2O = 49,74mol%) |
| Coefficient ya EO / nimugoroba•V-1 | r61= 6.07 | r61= 9.89 (Li2O = 49,95mol%) |
| Coefficient idafite umurongo /pm•V-1 | d33= 19.5 | d33= 23.8 |
| Kwiyuzuza amafoto | 1×10-5 | 10×10-5 (Li2O = 49.8mol%) |
| Igisubizo cyo gufotora igihe / s | amagana | ～0.6 (Li2O = 49.8mol%, Icyuma-cyuzuye) |
| Kurwanya gufotora / kwat•cm-2 | 100 | 104 (Li2O = 49.5-48.2mol%, 1.8mol% MgO ikoporora) |
| Imiterere ya flip amashanyarazi yumuriro / kV•mm-1 | 21 | 5 (Li2O = 49.8mol%) |
Ugereranije naCLNhamwe nibihimbano bimwe, ibyinshi mubintu byaSLNbyahinduwe muburyo butandukanye.Ibyingenzi byingenzi birimo:
(1) Wdoping ya hether fotora, doping anti-Photorefractive doping cyangwa laser ikora ion doping,SLN ifitebirenze imikorere yimikorere.Kong n'abandi.basanze iyo [Li] / [Nb] igeze kuri 0,995 naho ibirimo magnesium ni 1.0mol%, birwanya gufotora kwaSLNirashobora kugera kuri MW 26 / cm2, ni 6 byateganijwe ubunini burenze ubwoCLNhamwe na hamwe.Doping ya Photorefractive na laser-ikora ion doping nayo igira ingaruka zisa.
(2) Nkumubare winenge ya lattice muriSLNkristu igabanuka cyane, niko imbaraga zo guhatira imbaraga za kristu, hamwe na voltage isabwa kugirango polarisiyasi igabanuke igabanuka kuva kuri 21 kV / mm(ya CLN)kugeza kuri 5 kV / mm, bifite akamaro kanini mugutegura ibikoresho bya superlattice.Byongeye, amashanyarazi ya domaine imiterere yaSLNni Bisanzwe kandi inkuta za domaine ziroroshye.
(3)Amashanyarazi menshiIndangabintu yaSLNnazo zateye imbere cyane, nka coefficient ya electro-optiquer61yiyongereyeho 63%, coefficient idafite umurongo yiyongereyeho 22%, kristal birefringence yiyongereyeho 43% (uburebure bwa 632.8 nm), ihinduka ry'ubururuya UVinkombe,
