Isubiramo muri make Litiyumu Niobate Crystal hamwe nuburyo bukoreshwa - Igice cya 3: Kurwanya Doping ya Anti-Photorefractive LN Crystal

Ingaruka ya Photorefractive niyo shingiro rya optique ya holographique, ariko kandi izana ibibazo mubindi bikoresho bya optique, bityo rero kunoza fotorefractive irwanya lithium niobate kristal byitabweho cyane, muribwo buryo bwa doping aribwo buryo bwingenzi.Bitandukanye na doping ifotora, doping anti-Photorefractive ikoresha ibintu bifite valent idahinduka kugirango igabanye ikigo gifotora.Mu 1980, byavuzwe ko kwihanganira gufotora kwinshi kwa Mg-dope LN kristu yiyongera inshuro zirenga 2 z'ubunini, bikurura abantu benshi.Mu 1990, abashakashatsi basanze zinc-dope LN ifite imbaraga zo kurwanya fotorefratifike nka LN ya magnesium.Nyuma yimyaka itari mike, scandium-dope na indium-dope LN wasangaga ifite imbaraga zo kurwanya ifoto.

Mu 2000, Xu n'abandi.yavumbuye iyo hejuruIkigereranyo MgLNkristu hamwe na Photorefractive resistance murwego rugaragara hasimikorere myiza yo gufotora muri UV band.Ubu buvumbuzi bwaciwe no gusobanukirwaiKurwanya amafoto yaLNkristu, kandi yuzuza ubusa ibikoresho bifotora bikoreshwa mumutwe wa ultraviolet.Uburebure bugufi busobanura ko ingano ya golographeque ishobora kuba ntoya kandi nziza, kandi irashobora guhanagurwa no kwandikwa muri gritingi yumucyo ultraviolet, hanyuma igasomwa numucyo utukura nicyatsi kibisi, kugirango tumenye ikoreshwa rya optique ya holographique optique. .Lamarque n'abandi.yakiriye hejuruikigereranyo M.gLN kristu yatanzwe na kaminuza ya Nankai nka UV ifotoraibikoreshokandi yatahuye programable ebyiri-laser marike ukoresheje imirongo ibiri-ifatanije urumuri rwinshi.

Mubyiciro byambere, anti-Photorefractive doping element zirimo ibintu bisa kandi bigereranywa nka magnesium, zinc, indium na scandium.Muri 2009, Kong n'abandi.yateje imbere anti-Photorefractive doping ukoresheje tetraibintu bifite agaciro nka hafnium, zirconium na tin.Iyo ugeze kumurwanya umwe wo gufotora, ugereranije nibintu bigereranijwe kandi bigereranijwe, doping yibintu bya tetradvalent ni bike, kurugero, 4.0 mol% hafnium na 6.0 mol% magnesium dopedLNkristu ifite similarKurwanya amafoto,2.0 mol% zirconium na 6.5 mol% magnesium ikopororaLNkristu ifite similarKurwanya amafoto.Byongeye kandi, coefficente yo gutandukanya hafnium, zirconium na tin muri lithium niobate yegereye 1, bikaba byiza cyane mugutegura kristu nziza.
