Photorefractive effect ke motheo oa holographic optical applications, empa e boetse e tlisa mathata ho lits'ebetso tse ling tsa optical, kahoo ho ntlafatsa ho hanyetsa photorefractive ea lithium niobate kristale e lebisitsoe tlhokomelo e kholo, eo har'a eona molao oa doping e leng mokhoa oa bohlokoa ka ho fetisisa.Ho fapana le photorefractive doping, anti-photorefractive doping e sebelisa likarolo tse nang le valent e sa fetoheng ho fokotsa setsi sa photorefractive.Ka 1980, ho ile ha tlalehoa hore khanyetso ea photorefractive ea tekanyo e phahameng ea Mg-doped LN crystal e eketseha ka litaelo tse fetang 2 tsa boholo, tse ileng tsa khahla tlhokomelo e kholo.Ka 1990, bafuputsi ba fumane hore zinc-doped LN e na le khanyetso e phahameng ea photorefractive e ts'oanang le LN ea magnesium-doped.Lilemo tse 'maloa hamorao, LN ea scandium-doped le indium-doped LN e ile ea fumanoa e na le khanyetso ea photorefractive hape.

Ka 2000, Xu et al.sibollotse holimo hookarolelano Mg-dopedLNkristale e nang le khanyetso e phahameng ea photorefractive ka har'a sehlopha se bonahalang hasts'ebetso e ntle ea photorefractive sehlopheng sa UV.Ho sibolloa hona ho ile ha phunyeletsa kutloisisong eathephotorefractive resistance ofLNkristale, hape e ile ea tlatsa sekheo sa lisebelisoa tsa photorefractive tse kentsoeng sehlopheng sa ultraviolet.The wavelength e khuts'oane e bolela hore boholo ba grating ea holographic e ka ba nyane le ho feta, 'me e ka hlakoloa ka matla le ho ngoloa ka har'a grating ka leseli la ultraviolet,' me e baloe ka leseli le lefubelu le leseli le letala, e le ho hlokomela ts'ebeliso ea matla a holographic optics. .Lamarque et al.amohela tse phahamengtekanyo Mg-dopedLN kristale e fanoeng ke Univesithi ea Nankai e le UV photorefractivethepale ho lemohuoa ka mokhoa o hlophisehileng oa laser oa likarolo tse peli ka ho sebelisa matlafatso ea khanya ea maqhubu a mabeli.

Mothating oa pele, li-anti-photorefractive doping elements li ne li kenyeletsa divalent le trivalent elements tse kang magnesium, zinki, indium le scandium.Ka 2009, Kong et al.e hlahisitse li-anti-photorefractive doping tse sebelisang tetralikarolo tsa valent tse kang hafnium, zirconium le tin.Ha ho fihleloa khanyetso e ts'oanang ea photorefractive, ha e bapisoa le li-doped elements tsa divalent le trivalent, palo ea doping ea likarolo tsa tetradvalent e tlase, mohlala, 4.0 mol% hafnium le 6.0 mol% magnesium dopedLNlikristale li na le similarho hanyetsa photorefractive,2.0 mol% zirconium le 6.5 mol% magnesium e fokotsehileLNlikristale li na le similarho hanyetsa photorefractive.Ho feta moo, coefficient ea karohano ea hafnium, zirconium le tin ka lithium niobate e haufi le 1, e leng molemo haholo bakeng sa ho lokisetsa likristale tsa boleng bo phahameng.
