Photorefractive nyhuv yog lub hauv paus ntawm holographic kho qhov muag daim ntaub ntawv, tab sis nws kuj coj teeb meem rau lwm yam kho qhov muag daim ntaub ntawv, yog li kev txhim kho cov photorefractive kuj ntawm lithium niobate siv lead ua tau them zoo mloog, ntawm cov kev cai doping yog txoj kev tseem ceeb tshaj plaws.Hauv kev sib piv rau photorefractive doping, anti-photorefractive doping siv cov ntsiab lus uas tsis muaj qhov sib txawv los txo qhov chaw photorefractive.Xyoo 1980, nws tau tshaj tawm tias qhov kev tiv thaiv photorefractive ntawm qhov sib piv siab Mg-doped LN siv lead ua tau nce ntau dua 2 qhov kev txiav txim ntawm qhov loj, uas tau nyiam ntau yam.Xyoo 1990, cov kws tshawb fawb pom tias zinc-doped LN muaj cov duab hluav taws xob siab zoo ib yam li magnesium-doped LN.Ob peb xyoos tom qab ntawd, scandium-doped thiab indium-doped LN tau pom tias muaj photorefractive tsis kam thiab.

Xyoo 2000, Xu et al.pom tias siabpiv Mg-dobLNCrystal nrog siab photorefractive kuj nyob rau hauv pom band haszoo heev photorefractive kev ua tau zoo nyob rau hauv UV band.Qhov kev tshawb pom no tawg los ntawm kev nkag siab ntawmtusphotorefractive tsis kam ntawmLNsiv lead ua, thiab tseem tau ntim cov khoom tsis muaj photorefractive siv nyob rau hauv ultraviolet band.Lub luv luv wavelength txhais tau hais tias qhov loj ntawm holographic grating yuav me dua thiab finer, thiab yuav dynamically erased thiab sau rau hauv lub grating los ntawm ultraviolet lub teeb, thiab nyeem tawm los ntawm lub teeb liab thiab lub teeb ntsuab, thiaj li yuav paub txog daim ntawv thov ntawm dynamic holographic optics. .Lamarque et al.saws lub siabpiv Mg-dobLN Crystal muab los ntawm Nankai University raws li UV photorefractivekhoomthiab pom tau hais tias programmable ob-dimensional laser npav los ntawm kev siv ob-yoj txuas txuas lub teeb amplification.

Nyob rau hauv thaum ntxov theem, anti-photorefractive doping ntsiab suav nrog divalent thiab trivalent ntsiab xws li magnesium, zinc, indium thiab scandium.Xyoo 2009, Kong et al.tsim anti-photorefractive doping siv tetraCov khoom tseem ceeb xws li hafnium, zirconium thiab tin.Thaum ua tiav tib lub photorefractive kuj, piv nrog divalent thiab trivalent doped ntsiab, doping tus nqi ntawm tetradvalent ntsiab yog tsawg, piv txwv li, 4.0 mol% hafnium thiab 6.0 mol% magnesium doped.LNcrystals muaj similarphotorefractive tsis kam,2.0 mol% zirconium thiab 6.5 mol% magnesium dopedLNcrystals muaj similarphotorefractive tsis kam.Ntxiv mus, kev sib cais coefficient ntawm hafnium, zirconium thiab tin hauv lithium niobate yog ze rau 1, uas yog qhov zoo dua rau kev npaj cov khoom siv lead ua zoo.
