Uma kuqhathaniswa neevamile LNikristalu(CLN)ngokwakhiwa okufanayo, ukuntuleka kwe-lithium eduze-i-stoichiometricLNikristalu(SLN)kuholela ekunciphiseni okuphawulekayo kokukhubazeka kwe-lattice, futhi izakhiwo eziningi zishintsha ngokufanele.Ithebula elilandelayo libala okuyinhlokoumehluko weizakhiwo zomzimba.
Ukuqhathaniswa Kwezakhiwo phakathi kwe-CLN ne-SLN
| Impahla | I-CLN | I-SLN |
| I-Birefringence /633nm | -0.0837 | -0.0974 (Li2O=49.74mol%) |
| I-EO coefficient /pm•V-1 | r61=6.07 | r61=9.89 (Li2O=49.95mol%) |
| I-coefficient engaqondile /pm•V-1 | d33=19.5 | d33=23.8 |
| Ukugcwaliswa kwe-Photorefractive | 1×10-5 | 10×10-5 (Li2O=49.8mol%) |
| Isikhathi sokuphendula se-Photorefractive /s | amakhulu | ～0.6 (Li2O=49.8mol%, I-ayina-doped) |
| Ukumelana ne-Photorefractive /kW•cm-2 | 100 | 104 (Li2O=49.5-48.2mol%, 1.8mol% MgO doped) |
| Isizinda siphendukisa ukuqina kwenkundla kagesi /kV•mm-1 | 21 | 5 (Li2O=49.8mol%) |
Uma kuqhathaniswa neI-CLNngokwakheka okufanayo, izici eziningi zeI-SLNathuthukisiwe ngamazinga ahlukahlukene.Ukulungiselela okubaluleke kakhulu kuhlanganisa:
(1) Wnoma i-doping ye-photorefractive, i-anti-photorefractive doping noma i-laser-activated ion doping,I-SLN ineumphumela wokulawula ukusebenza obucayi kakhulu.Kong et al.ithole ukuthi uma i-[Li]/[Nb] ifinyelela ku-0.995 futhi okuqukethwe kwe-magnesium kungu-1.0mol%, ukumelana ne-photorefractiveI-SLNingafinyelela ku-26 MW/cm2, okungama-oda angu-6 obukhulu ngaphezu kwalokho kweI-CLNngokwakhiwa okufanayo.I-Photorefractive doping kanye ne-laser-activated ion doping nayo inemiphumela efanayo.
(2) Njengoba inani le-lattice lingasebenzi kahleI-SLNikristalu incipha kakhulu, kanjalo namandla enkambu yekristalu ayancipha, namandla kagesi adingekayo ukuze kuguqulwe i-polarization ayehla esuka cishe ku-21 kV/mm.(ye-CLN)cishe ku-5 kV/mm, okuzuzisa kakhulu ukulungiswa kwemishini ye-superlattice.Ngaphezu kwalokho, isakhiwo sesizinda sikagesi seI-SLNivamile futhi izindonga zesizinda zibushelelezi.
(3)Ama-photoelectric amaningiizakhiwo zeI-SLNnazo zithuthukisiwe kakhulu, njenge-electro-optic coefficientr61inyuke ngo-63%, i-coefficient engaqondile ikhuphuke ngo-22%, i-crystal birefringence inyuke ngo-43% (ubude begagasi 632.8 nm), ukushintsha okuluhlaza okwesibhakabhakakwe-UVumphetho wokumuncwa, njll.
