Potassium dideuterium phosphate (DKDP) waa nooc ka mid ah muraayadaha indhaha ee aan toosnayn oo leh sifooyin koronto-optic oo aad u wanaagsan oo la sameeyay 1940-meeyadii. Waxaa si weyn loogu isticmaalaa oscillation parametric indhaha, electro-optic Q-damasho, Hababka Electro-optic iyo wixii la mid ah. DKDP crystal ayaa lehlaba waji: wajiga monoklinik iyo wejiga tetragonal. The faa'iido leh DKDP crystal waa wejiga tetragonal kaas oo iska leh D_2d-42m kooxda dhibic iyo aqoonsiga¹²_2d -42d kooxda meel bannaan. DKDP waa isomorphicqaab dhismeedka potassium dihydrogen phosphate (KDP). Deuterium waxay ku beddeshaa hydrogen gudaha KDP crystal si loo baabi'iyo saameynta nuugista infrared ee uu keeno gariirka hydrogen.DKDP crystal leh jiirka deuteration sareio ayaa leh electro-optical ka fiican guryaha iyo ka fiican guryaha aan tooska ahayn.

Tan iyo 1970-yadii, horumarinta laser Idhexdhexaad ah Cganaaxid Ftignoolajiyada isticmaalka (ICF) ayaa si weyn kor ugu qaaday horumarinta taxane ah kiristaalo korantada, gaar ahaan KDP iyo DKDP. Sida ah Electro-optical iyo qalabka indhaha ee aan toos ahayn loo isticmaalo ICF, crystal waa loo baahan yahay inuu yeesho gudbin sare xadhkaha hirarka ka U dhow-ultraviolet ilaa infrared-ku-dhow, isku-dhafan koronto-optical-ka weyn iyo isku-xidhka aan tooska ahayn, heerka waxyeellada sare, iyo ahaansho karti u leh ahaansho diyaarid in dalool weyn iyo leh tayada sare ee indhaha. Ilaa hadda, kaliya KDP iyo DKDP crystals la kulmose shuruudaha.

ICF waxay u baahan tahay cabbirka DKDP qayb si ay u gaaraan 400 ~ 600 mm. Caadi ahaan waxay qaadataa 1-2 sano si ay u koraanDKDP crystal leh sida weyn oo kale iyadoo la raacayo habka dhaqanka ee qaboojinta xal aqueous, sidaas darteed shaqo badan oo cilmi-baaris ah ayaa la fuliyay helid koritaanka degdega ah ee kiristaalo DKDP. Sannadkii 1982, Bespalov et al. bartay tignoolajiyada kobaca degdega ah ee crystal DKDP oo leh qayb iskutallaab ah oo 40 mm ah×40 mm, heerka kobacana waxa uu gaadhay 0.5-1.0 mm/h, kaas oo ahaa amar ka sarreeya habka caadiga ah. Sannadkii 1987, Bespalov et al. si guul leh u koray kiristaalo tayo sare leh oo DKDP ah cabbirka 150 mm×150 mm×80 mm by iyadoo la isticmaalayo farsamo korriin degdeg ah oo la mid ah. Sannadkii 1990-kii, Chernov et al. laga helay kiristaalo DKDP oo leh tiro dhan 800 g iyadoo la isticmaalayo dhibic-habka abuur. Heerka kobaca ee kiristaalo DKDP gudaha Z-jihada la gaarod 40-50 mm/d, iyo kuwa ku jira X- iyo Y-tilmaamo gaadhidd 20-25 mm/d. Lawrence Livermore Qaran Shaybaadhka (LLNL) wuxuu sameeyay cilmi-baaris badan oo ku saabsan diyaarinta kiristaalo KDP-ga weyn iyo kiristaalo DKDP ee baahiyaha Ndhexdhexaad ah Qalabka Dabka (NIF) ee USA. 2012,Cilmi-baarayaasha Shiinaha ayaa horumariyay crystal DKDP ah oo cabbirkiisu yahay 510 mm×390 mm×520 mm kaas oo ka kooban nooc cayriin DKDP ah II soo noqnoqda labanlaabma oo cabbirkeedu ahaa 430 mm sameeyey.

Codsiyada beddelka Q-electro-optical-ka waxay u baahan yihiin kiristaalo DKDP oo leh nuxurka deuterium sare. Sannadkii 1995, Zaitseva et al. koray DKDP crystals oo leh maadada deuterium sare iyo heerka korriinka 10-40 mm/d. Sannadkii 1998, Zaitseva et al. Kiristaalo DKDP ah oo la helay oo leh tayo muuqaal wanaagsan, cufnaanta kala-baxa hooseeya, lebbiska indhaha sare iyo heerka dhaawaca sare iyadoo la adeegsanayo habka sifaynta joogtada ah. Sannadkii 2006, habka sawir-qaadista ee beerista kristal deuterium sare ee DKDP ayaa la sharciyeeyay. Sannadka 2015, DKDP waxay la socotaa jiirka goyntaio 98% iyo cabbirka 100 mm×105 mm×96 mm ayaa si guul leh loogu koray dhibic-abuur habka ee Jaamacadda Shandong ee Shiinaha. Thwaa crystal ma laha cillad macro muuqda, iyo ay Asymmetry index refractive ayaa ka yar 0.441 ppm. 2015, tignoolajiyada kobaca degdega ahee DKDP crystal oo leh jiirka deuterationio 90% ayaa markii ugu horeysay loo adeegsaday Shiinaha si loogu diyaariyo S-beddeloalaabta, caddaynta in tignoolajiyada kobaca degdega ah lagu dabaqi karo si loo diyaariyo 430 mm dhexroor DKDP electro-optical Q-switching qayb waxaa looga baahan yahay ICF.

DKDP crystal waxaa sameeyay WISOPTIC (Deuteration> 99%)

Kiristaalo DKDP soo bandhigay jawiga muddo dheer ayaa doona leeyihiin oogada oogada iyo nebulization, taas oo u horseedi doonta hoos u dhac weyn oo ku yimaada tayada indhaha iyo luminta waxtarka beddelidda. Sidaa darteed, waxaa lagama maarmaan ah in la xiro crystal-ka marka la diyaarinayo koronto-optic Q-switch. Si loo yareeyo milicsiga iftiinkaon daaqadda xidhitaankas ee Q-switch iyo on the sagxadaha badan ee crystal-ka, dareeraha isbarbardhiga index refractive ayaa inta badan lagu duraa meel bannaan inta u dhaxaysa crystal iyo daaqaddas. Xataa wka saarin anti-dahaarka milicsiga, tisaga gudbin noqon kara korodhay 92% ilaa 96%-97% (wavedherer 1064 nm) by isticmaalaya xal u dhigma index refractive. Intaa waxaa dheer, filimka ilaalinta ayaa sidoo kale loo isticmaalaa sida cabbirka qoyaanka. Xionget al. diyaariyey SiO₂ filim colloidal leh hawlaha qoyaan-ka-hortagga iyo ka-hortagga-milicsigaon. gudbinta ayaa gaadhay 99.7% (mawjadaha dhererka 794 nm), iyo heerka waxyeelada laysarka ayaa gaadhay 16.9 J/cm² (dhererka hirarka 1053 nm, ballaca garaaca wadnaha 1 ns). Wang Xiaodong iyo al. la diyaariyey a filim difaac by iyadoo la isticmaalayo xabagta dhalada polysiloxane. Heerka waxyeelada laysarka ayaa gaadhay 28 J/cm² (mawjadaha dhererka 1064 nm, ballaca garaaca wadnaha 3 ns), iyo guryaha indhaha ayaa si cadaalad ah ugu xasiloon deegaanka oo leh qoyaan qaraabo ka sarreeya 90% muddo 3 bilood ah.

Ka duwan crystal LN, si looga adkaado saamaynta birefringence dabiiciga ah, DKDP crystal inta badan waxay qabataa qaabaynta dhererka Marka electrode giraanta la isticmaalo, dhererka crystal in theqoryo jihada waa in ay ka weyn tahay crystal’s dhexroor, si ay u helaan beer koronto isku mid ah, kuwaas oo sidaas darteed kordhiyaa nuugista iftiinka ee crystal iyo saamaynta kulaylku waxay u horseedi doontaa depolarization at celceliska awoodda sare.

Iyada oo la raacayo baahida ICF, diyaarinta, farsamaynta iyo tignoolajiyada codsiga ee DKDP crystal ayaa si degdeg ah loo horumariyay, taas oo ka dhigaysa DKDP electro-optic Q-switchs in si weyn loogu isticmaalo daawaynta laysarka, bilicda laysarka, xaradhka laysarka, calaamadaynta laysarka, cilmi-baadhis cilmiyeed iyo qaybaha kale ee codsiga laser. Si kastaba ha ahaatee, liidashada, luminta gelinta sare iyo awood la'aanta in lagu shaqeeyo heerkul hooseeya ayaa weli ah caqabadaha xaddidaya codsiga ballaaran ee kiristaalo DKDP.
