Posachedwa, Institute of Intervics of the Russian Academy of Science imayambitsa kafukufuku wa exawatt kuti muphunzire kwambiri (XCELS), pulogalamu yofufuzira yamagetsi yayikulu kwambiriMphamvu zamphamvu. Pulojekitiyi imaphatikizapo kumanga kwamphamvu yayikuluKutengera ndi ma pormetric chorse orse orse onlicy m'matumbo akulu potaziyamu phosphate (dkdp, mankhwala owoneka bwino, omwe amayembekezeredwa kwathunthu kwa magetsi a ma 600 pw. Ntchitoyi imapereka chidziwitso chofunikira komanso kafukufuku wofufuza za ntchito ya xcels ndi machitidwe ake a laser, pofotokoza ntchito komanso zomwe zingachitike pokhudzana ndi mgwirizano wa ultra-mphamvu.
Pulogalamu ya XCELS idafunsidwa mu 2011 ndi cholinga choyambirira chokwaniritsa mphamvu ya peaklaserKutulutsa kwapakutu kwa 200 pw, komwe sikunakhazikitsidwe mpaka 600 pw. ZaDongosolo la Laseramadalira matekinoloje atatu:

Mafayilo a Ultra-Pafupifupi amapezeka kwambiri m'makhiristo ambiri ndipo amagwiritsidwa ntchito ku OPCPA femtundondi. Makhiristo a DKDP amagwiritsidwa ntchito chifukwa ndi zokhazo zomwe zimapezeka kuti zikuchitika kwa masentimita a masentimita a masentimita ndipo nthawi yomweyo yakhala ndi mikhalidwe yovomerezeka yothandizira kukulitsa mphamvu ya mage-pwmalavu. Zimapezeka kuti DKDP Crystal imadulidwa ndi kuwunika kwapang'onopang'ono kwa bulose ya ntragu ya ND, ngati chonyamulira cha amplified ndi 910 nm, mawu oyamba atatu a Taylor Kukula kwa Hip Vector ndi 0.
Chithunzi 1 ndi mawonekedwe osafunikira a xces aser. Mapeto akumaso omwe amapangidwa ndi femtosecond pulses ndi Highleghtth ya 910 nm (1.3 nm (1.3 nm (1.3 nm (1.3 nm (1.3 nm (1.3 nm (1.3 nm (1.3 nm (1.3 NM 1) ndi 1054 nm nanoseccond zosemphana ndi opcpa (1.1 ndi 1.2 mu Chithunzi 1). Kutsogolo kumatsimikiziranso kulumbira kwa mafilimuwa komanso magawo omwe amafunikira mphamvu ndi zigawo zina. Wopcpa wapakatikati pano wobwereza kungobwereza kwapamwamba (1 HZ) akuwakonzera chiwembu cholumikizidwa kwa abale anu (2 Chithunzi 1). Ngozi imakwezedwa ndi chilimbikitso cha OPCVA kulowa mumiyala imodzi ya kilojoule ndikugawika mumiyala 12 yofananira (4 pa Chithunzi 1). Omaliza 12 a Opcpa, aliyense wa kuwala kwa 12 omwe akwezedwa amakulitsidwa mpaka pamlingo wa kilojoule (5 mu Chithunzi 1) kenako ndikukakamizidwa ndi ma greamiction 12 pa Chithunzi 1). Zosefera za acousto-zoptic optic zimagwiritsidwa ntchito kumapeto kwa ma velocity ogwiritsira ntchito omwe amabalalika ndikubalalika kwambiri, kuti athe kupeza m'lifupi kakang'ono kwambiri. Mphamvu yamphamvu ili ndi mawonekedwe pafupifupi a 12th Speauss, ndi Spectridth pa 1% ya mtengo wambiri ndi 150 nm, zogwirizana ndi masinthidwe anayi a FS. Poganizira zolipira zosakwanira zofananira ndi zovuta zomwe sizikugwirizana ndi gawo losagwirizana ndi a Armtric Amprifaraers, omwe amayembekezeredwa ndi 20 FS.
Oseri a XCELS agwiritsa ntchito ma 8-channel-2m nedymium galasi laser osewerera ma module osenda (3 pa Chithunzi 1), pomwe ma njira 13 adzagwiritsidwa ntchito kupukusa chitoto ndi 12 Fitcpa. Makina atatu otsalawo adzagwiritsidwa ntchito ngati nanosecondi yodziyimira poyipitsiramagwero a laserpa zoyeserera zina. Kuchepa ndi kusokonekera kwa ma ckdp makhiristo, kulimba kwa kugunda kwa kugunda kwa 1.5 gw / cm2 pa njira iliyonse ndi nthawi ya 3.5 NS.
Njira iliyonse ya xcels laser imatulutsa mapiritsi ndi mphamvu ya 50 pw. Makina onse 12 amapereka mphamvu zokwanira 600 pw. Mu chipinda chachikulu cha chandamale, kuchuluka kwakukulu kwa njira iliyonse pansi pa mikhalidwe yabwino ndi 0.44 × 1025 w / cm2, 1 zinthu zomwe zimagwiritsidwa ntchito poyang'ana. Ngati kukoka kwa njira iliyonse kumangirizidwanso ndi njira ya anthu 2.6 ndi njira yophatikizira, mphamvu yofananira idzachulukitsa mpaka 230 pw, mphamvu yofananira yolingana ndi ma pw, olingana ndi kuwala kwa kutentha kwa 2.0 × 1025 w / cm2.
Kuti mukwaniritse kukula kwakukulu, pa 600 pw kutulutsa, Kuwala kumapaka munjira 12 kudzaonetsedwa mu ma radiation 2. Ngati gawo lirilonse lotsekedwa ndi lolumikizana, Kuwala kwa SountSent Kuwala kudzawonjezeka mpaka 3.2 × 1026 w / cm2. Kuphatikiza pa chipinda chachikulu chandamale, ntchito ya XCELS imaphatikizapo ma labotore a ogwiritsa ntchito 10, aliyense kulandira mitengo imodzi kapena zingapo zoyeserera. Pogwiritsa ntchito gawo lowala bwino kwambiri, mapulani a XCELLS Project kuti ayesere kuyesa m'magulu anayi: centum elecyynaynamics njira mu minda ya laser; Kupanga ndi kuthamanga kwa tinthu; M'badwo wa ma elekiti yachiwiri yamagetsi; Laboratory Alwepysics, mphamvu yayikulu kwambiri komanso kafukufuku wofufuza.
CHITH. 2 poyang'ana geometry m'chipinda chachikulu chandamale. Zomveka
Chithunzi 3 chikuwonetsa malo owoneka bwino a gawo lililonse la xces laser mu nyumba yoyesera. Magetsi, mapa magetsi, mapampu, chithandizo chamadzi, kuyeretsedwa ndi zowongolera mpweya zili m'chipinda chapansi. Malo onse omangawo ndi oposa 24,000 m2. Magetsi onse omwe amagwiritsidwa ntchito ndi pafupifupi 7.5 mw. Nyumba yoyesera imakhala ndi chivomerezi chamkati komanso gawo lakunja, aliyense amapangidwira pamaziko awiri. The vacuram ndi njira zina zokutira zimayikidwa pa kugwedezeka kwa malo okhala mosapita m'mbali, kotero kuti matalikidwe a kusokonezeka kwa laser kudzera pa maziko ndi ma hz okwanira 1-200 hz. Kuphatikiza apo.
Ntchito ya XCELS ikufuna kupanga malo ofufuza asayansi a sayansi chifukwa cha kuchuluka kwamphamvu kwambiri kwa ma lasers. Njira imodzi ya xces laser dongosolo imatha kupereka kukula kwakukulu kangapo kuposa 1024 w / cm2, yomwe imatha kupitirira 1025 w / cm2 ndi ukadaulo wophatikizika. Ndi diplele-pompoponda kuchokera ku ma apulogalamu 12 mu laser system, kulimba mtima pafupi ndi 1026 w / cm2 kumatheka ngakhale popanda kutembenuka ndi gawo latseke. Ngati gawo la magawo pakati pa ma annel limatsekedwa, kuwala kwa kuwalako kudzakhala kupitirira kangapo. Pogwiritsa ntchito mphamvu zojambulajambulazi ndi zomangirazi. Izi zimagwira ntchito yapadera mu gawo la Super-Final electromagnetic Garnics yoyesera.
