Xa kuthelekiswa neeqhelekileyo LNikristale(CLN)kunye nokubunjwa okufanayo, ukungabikho kwe-lithium kufuphi-stoichiometricLNikristale(SLN)kukhokelela ekunciphiseni okubonakalayo kweziphene ze-lattice, kwaye iipropati ezininzi zitshintsha ngokufanelekileyo.Le theyibhile ilandelayo idwelisa eyona iphambiliiyantlukwano zeiimpawu zomzimba.
Ukuthelekiswa kweePropati phakathi kwe-CLN kunye ne-SLN
| Ipropati | I-CLN | SLN |
| I-Birefringence / 633nm | -0.0837 | -0.0974 (Li2O=49.74mol%) |
| EO i-coefficient /pm•V-1 | r61=6.07 | r61=9.89 (Li2O=49.95mol%) |
| I-Coefficient engahambelaniyo /pm•V-1 | d33=19.5 | d33=23.8 |
| Ifotorefractive saturation | 1×10-5 | 10×10-5 (Li2O=49.8mol%) |
| Ixesha lokuphendula nge-Photorefractive | amakhulu | ～0.6 (Li2O=49.8mol%, Iron-doped) |
| Ukuxhathisa i-Photorefractive / kW•cm-2 | 100 | 104 (Li2O=49.5-48.2mol%, 1.8mol% MgO doped) |
| I-Domain flip amandla ebala lombane /kV•mm-1 | 21 | 5 (Li2O=49.8mol%) |
Xa kuthelekiswa neI-CLNkunye nokwakheka okufanayo, uninzi lweempawu zeSLNziphuculwe ngokwamanqanaba ahlukeneyo.Olona lungiselelo lubaluleke ngakumbi lubandakanya:
(1) Wnokuba idoping ye-photorefractive, i-anti-photorefractive doping okanye i-laser-activated ion doping,I-SLN iyeisiphumo esithe kratya solawulo lwentsebenzo.Kong et al.ifumene ukuba xa [Li]/[Nb] ifikelela kwi-0.995 kwaye umxholo we-magnesium ngu-1.0mol%, ukuchasana kwe-photorefractiveSLNinokufikelela kwi-26 MW / cm2, eyi-6 imiyalelo yobukhulu obungaphezulu kunobo beI-CLNkunye nokwakheka okufanayo.I-Photorefractive doping kunye ne-laser-activated ion doping nazo zineziphumo ezifanayo.
(2) Njengoko inani leletiyisi izipheneSLNIkristale iyancipha kakhulu, ngokunjalo amandla entsimi yokunyanzeliswa kwekristale, kwaye amandla ombane afunekayo ukuguqulwa kwepolarization ayancipha ukusuka malunga ne-21 kV/mm.(ye-CLN)ukuya malunga ne-5 kV/mm, eluncedo kakhulu ekulungiseleleni izixhobo ze-superlattice.Ngaphezu koko, isakhiwo sommandla wombane weSLNiqhelekile kwaye iindonga zommandla zigudile.
(3)Uninzi lweefoto zombaneiipropati zeSLNzikwaphuculwe kakhulu, njenge-electro-optic coefficientr61inyuke nge-63%, i-coefficient engabonakaliyo inyuke nge-22%, i-crystal birefringence inyuke nge-43% (ubude be-632.8 nm), i-blue shiftyeUVedge yokufunxa, njl.
