Sakamakon Photorefractive shine tushen aikace-aikacen gani na holographic, amma kuma yana kawo matsaloli ga sauran aikace-aikacen gani, don haka an ba da kulawa sosai ga haɓaka juriya na ɗaukar hoto na lithium niobate crystal, tsakanin waɗanda tsarin doping shine hanya mafi mahimmanci.Ya bambanta da doping na photorefractive, anti-photorefractive doping yana amfani da abubuwa tare da valent maras canzawa don rage cibiyar photorefractive.A cikin 1980, an ba da rahoton cewa juriya na ɗaukar hoto na babban rabo na Mg-doped LN crystal yana ƙaruwa da fiye da umarni 2 na girma, wanda ya jawo hankali sosai.A cikin 1990, masu bincike sun gano cewa zinc-doped LN yana da babban juriya na hoto mai kama da magnesium-doped LN.Shekaru da yawa bayan haka, an gano scandium-doped da indium-doped LN suna da juriya na hoto suma.

A cikin 2000, Xu et al.gano cewa highrabo Mg-dopedLNcrystal tare da high photorefractive juriya a bayyane band haskyakkyawan aikin photorefractive a cikin band UV.Wannan binciken ya warware ta hanyar fahimtardaphotorefractive juriya naLNcrystal, da kuma cike da sarari na photorefractive kayan shafa a cikin ultraviolet band.Matsakaicin tsayin tsayi yana nufin cewa girman holographic grating na iya zama ƙarami kuma mafi kyau, kuma ana iya goge shi da ƙarfi kuma a rubuta shi a cikin grating ta hasken ultraviolet, kuma a karanta shi ta hanyar ja da hasken kore, don gane aikace-aikacen holographic optics mai ƙarfi. .Lamarque et al.rungumi highrabo Mg-dopedLN crystal wanda Jami'ar Nankai ta samar a matsayin UV photorefractiveabuda kuma gano alamar laser mai girma biyu mai iya shirye-shirye ta amfani da haɓaka haske mai raƙuman ruwa biyu.

A cikin matakin farko, abubuwan da ke hana daukar hoto da hana daukar hoto sun hada da divalent da abubuwa masu trivalent kamar su magnesium, zinc, indium da scandium.A cikin 2009, Kong et al.ɓullo da anti-photofractive doping ta amfani da tetraabubuwa masu mahimmanci kamar hafnium, zirconium da tin.Lokacin samun juriya iri ɗaya na photorefractive, idan aka kwatanta da divalent da trivalent abubuwan doped, adadin doping na abubuwan tetradvalent ya ragu, misali, 4.0 mol% hafnium da 6.0 mol% magnesium doped.LNlu'ulu'u suna da simirinjuriya na photorefractive,20 mol% zirconium da 6.5 mol% magnesium dopedLNlu'ulu'u suna da simirinjuriya na daukar hoto.Haka kuma, rarrabuwa coefficient na hafnium, zirconium da tin a lithium niobate yana kusa da 1, wanda ya fi dacewa don shirye-shiryen lu'ulu'u masu inganci.
