Kutshanje, iZiko leeFizi leSigadi saseRussia lazisa iziko le-Exiwatt ukuze kuphononongwe olugqithisileyo (i-xcels), inkqubo yophando yezixhobo ezikhulu zesayensi esekwe kakhuluI-Lasers ephezulu. Iprojekthi ibandakanya ukwakhiwa kwentoI-Leser ephezuluNgokusekwe kwi-pirse ye-pirse ye-chiped ye-pirse ye-apertire kwi-potaspharium ye-potasphate phosphate (i-DKDP, ifomula yekhemicamiki ye-600 ye-PWE. Lo msebenzi ubonelela ngeenkcukacha ezibalulekileyo kunye neziphumo zophando malunga neProjekthi ye-XCEL kunye neeNkqubo zaYo ze-laser, ezichaza izicelo kunye neempembelelo ezinokubakho ezinxulumene noxinzelelo lwe-Ultra.
Inkqubo ye-xcel yacetywa ngo-2011 ngenjongo yokuqala yokufezekisa amandla encophoi-laserI-Pulse Iphuli ye-200 PW, ephuculwe kwangoku i-600 PW. YayoInkqubo ye-laserIxhomekeke kwiitekhnoloji ezintathu eziphambili:
. Itekhnoloji ye-CPA);

Inqanaba le-Ultra-Oltra elibanzi lifunyanwa ngokubanzi kwiikristali ezininzi kwaye isetyenziswa kwi-Oppa FebtoseCond Lairs. Ikristali ye-DKDP isetyenziswa kuba zezona zinto zifunyenwe zikwenziwayo ezinokukhula zinokukhula kweesentimitha kwaye kwangaxeshanye zineempawu ezamkelekileyo ze-PWA-PWi-landlers. Kufunyanwa ukuba xa i-DKDP Crystal iphumelelwe kukuhamba kabini kwe-ND Leser ye-ND, ukuba umphathi wama-910 NM, amagama amathathu okuqala kwe-vector vector mistectch ngu-0.
Umzobo 1 sisiseko senkqubo ye-xcels ser yenkqubo. Isiphelo sangaphambili sivelise i-festosecond ye-phytosencond ye-910 NM (1.3 kumzobo 1) kunye ne-1054 nm nasecond i-essed i-orsed i-pume putser (1.2 kumzobo 1). Isiphelo sangaphambili siqinisekisa ungqamaniso lwezi khutywina kunye namandla afunekayo kunye neparameters efunekayo. I-Oppappa ephakathi isebenza kwixabiso eliphezulu lokuphindaphinda (i-1 Hz) lukhuthaza i-chird pulses ukuya kwishumi leentsuku (2 kumzobo 1). Ipulse iphinde yandiswa ngakumbi yi-opcpa i-opcpa ibe yi-tilojoule enye kwaye yahlulahlulwe yaba yi-12 efanayo Kwi-OPCPA yokugqibela ye-12 APCPA, nganye yezihlazo ezili-12 zokukhanya i-chirds ikhula kwinqanaba le-kilojoule (5 kumzobo 1) kwaye icinezelwe ngu-12 onoyolo (i-GC ye-6 kumzobo 1). Isihluzi se-ACOSTO-APPOCIC se-APOSTO-APT sisetyenziswe kwisiphelo sangaphambili ukuya kwiqela lokulawula ngokuthe ngqo kunye nokusasazeka okuphezulu, ukuze ufumane oko kububanzi bukhulu. I-pulse spectrum inemilo ye-odolo ye-odolo ye-12 ye-oda ye-odolo, kunye nebhendi ebonakalayo kwi-1% yexabiso eliphezulu yi-150 NM, ehambelana ne-Fiese Ububanzi be-17 fs. Ukujonga imbuyekezo engaphelelanga kunye nobunzima benqanaba le-NOLLANAL imbuyekezo kwiParametric Amplific Amplific Amplific, ububanzi obulindelekileyo bungama-20 fs.
I-xcels yase-Gcels iya kuqesha i-8mnel Ufl-2m Nest i-Laser i-Laser Rill Homents (3 kumzobo 1), eza kusetyenziswa i-opcpa ye-opct kunye ne-APCPA yokugqibela. Iindlela ezintathu ezisele ziya kusetyenziswa njenge-danosecond ezizimeleyo ye-nanojongesImithombo yase-laserkolunye uvavanyo. Ukunqongophala ngumgangatho wokuqhawula owakhiweyo we-DKDP, ubukhulu be-inradiation of pumple ifihliwe kwi-1.5 GW / CM2 kwisitishi ngasinye kwaye ixesha li-3.5 NS.
Ijelo ngalinye le-xcels laser ye-laseer livelisa i-pulses ngamandla angama-50 iphe. Itotali ye-12 iyonke ibonelela ngamandla apheleleyo aphuma kwi-600 PW. Kwigumbi eliphambili ekujoliso, elona nqanaba liphezulu lokugxila kwijelo ngalinye phantsi kweemeko ezifanelekileyo yi-0.44 × 1025 w / cm2, ukugxila kwezinto f / 1 ukugxila kwezinto ezisetyenziselwa ukugxila. Ukuba ipulse yejelo ngalinye icinezelwe ngakumbi kwi-2.6 FS ngendlela yokucinezela, amandla ahambelana nayo iya kunyuswa ibe yi-230 PW, ihambelana nobunzulu be-2.0 × 1025 w / cm2.
Ukufezekisa ubukhulu obukhulu bokukhanya, kwiziphumo ze-PW ezingama-600, ukukhanya kweendlela ezili-12 kuya kugxila kwi-geometry ye-gepole yemitha nganye akuboniswanga kwi-9 × 1025 w / cm2. Ukuba isigaba ngasinye sepulse sitshixiwe kwaye silungelelaniswe, ubukhali bokukhanya okukhohlakeleyo buya kwandiswa ukuya kwi-3.2 × 1026 w / cm2. Ukongeza kwigumbi lokujolisa eliphambili, iprojekthi ye-xcels ibandakanya ukuya kwi-10 yeelebhu zabasebenzisi, nganye ifumana imiqadi enye okanye engaphezulu yovavanyo. Sebenzisa le ntsimi inamandla kakhulu, iprojekthi ye-xcels iCwangciso lokwenza uvavanyo kumacandelo amane amane: ii-soum ze-elektrodnamics kwiinkqubo ze-laser; Imveliso kunye nokukhawulezisa amasuntswana; Isizukulwana semitha ye-elektromaricarner; I-Laboratory Astrophysics, iinkqubo zoxinzelelo lwamandla aphezulu kunye nophando lokuxilongwa.
IKHIWANE. 2 Ukugxila kwejometri kwigumbi lokujolisa kakhulu. Ukucaca, isipili separakosi somthi 6 sisekeleke ebonakalayo, kwaye igalelo kunye ne-Beams kunye ne-PAMED BONI BANYE KUPHELA ZIBHENO ZESITHATHU 1 NO-7
Umzobo 3 ubonakalisa ubume bendawo yendawo nganye esebenzayo ye-xcels yenkqubo yesakhiwo sovavanyo. Umbane, impompo ye-vacuum, unyango lwamanzi, ukucocwa kwamanzi kunye nemeko yomoya kufakwe kwigumbi elingaphantsi. Indawo epheleleyo yokwakha ingaphezulu kwe-24,000 m2. Ukusetyenziswa kwamandla kuphela malunga ne-7.5 MW. Isakhiwo sovavanyo sinesakhelo sangaphakathi esinamandla kunye necandelo langaphandle, ngalinye lakhiwe kwiziseko ezibini zenziwe. I-vacuum kunye nezinye iinkqubo zokuphembelela ezivunyiweyo zifakwe kwi-fibiration ye-vibration-esodwa, ukuze i-Alplity ye-Alltity idluliselwe kwinkqubo ye-ler kwi-10 ukuya kwi-G2 / HZ kwi-REARTEY ye-1-200 hz. Ukongeza, inethiwekhi ye-geodesic Transuters icwangciselwe kwiholo ye-laser ukuze ibeke iliso ngokucwangcisiweyo lomhlaba kunye nezixhobo.
Iprojekthi ye-xcels ijolise ekwenzeni indawo enkulu yophando lwenzululwazi esekwe kwi-Peap enkulu kakhulu yamandla. Ijelo elinye le-xcels lestem linokubonelela ngamandla agxile kakhulu kuno-1024 W / CM2, enokuqhubeka ngeteknoloji ye-1025 W / CM2 ngetekhnoloji yoxinzelelo. Ngokuphosa i-ripole-egxile kwiindlela ezili-12 kwi-Laser System, ubukhulu becala ku-1026 w / cm2 bunokufezekiswa ngaphandle koxinzelelo kunye nokutshintshwa kwesigaba. Ukuba ungqamaniso lwenqanaba phakathi kwamajelo luvaliwe, ubukhulu bokukhanya buya kuba ngaphezulu. Sebenzisa ezi zinto zibonisa irekhodi kunye nendawo ye-beam ye-beam ye-beam, iziko le-xcels liya kuba nakho ukwenza uvavanyo oluphezulu, ukusasazeka okukhulu kwendawo enobuninzi bemigangatho emininzi kunye ne-radiation yenqanaba le-Milti-Channey. Oku kuyakudlala indima ekhethekileyo kwicandelo le-super-stromagnetic yovavanyo lwe-Electromagnetic.
