Tignoolajiyada iyo isbeddellada horumarka ee laysarka attosecond ee Shiinaha

Machadka Fiisigiska, Akadeemiyada Sayniska Shiinaha, ayaa soo warisay natiijooyinka cabbirka ee 160 oo ah garaaca wadnaha attosecond ee go'doonsan ee 2013. Xakamaynta attosecond ee go'doonsan (IAPs) ee kooxdan cilmi-baarista ayaa la soo saaray iyadoo lagu saleynayo iswaafajinta nidaamka sare ee ay wadaan sub-5 femtosecond laser garaaca garaaca wadnaha oo xasiliyay by CEP. Astaamaha ku meel gaadhka ah ee garaaca wadnaha attosecond waxa lagu gartaa attosecond stretch spectroscopy. Natiijooyinku waxay muujinayaan in laydhkani uu bixin karo garaacyada attosecond ee go'doonsan oo leh muddada garaaca wadnaha ee 160 attose seconds iyo hirarka dhexe ee 82eV. Kooxdu waxa ay horumar ka samaysay jiilka attosecond iyo teknoolajiyada fidinta spectroscopy-ga labaad. Ilaha iftiinka ultraviolet ee aadka u daran ee leh xallinta attosecond ayaa sidoo kale furi doona goobo cusub oo codsi ah oo fiisigiska walxaha isku dhafan. 2018, Machadka Fiisigiska, Akadeemiyada Sayniska ee Shiinaha, ayaa sidoo kale ka warbixisay qorshe dhisme oo loogu talagalay aaladda isticmaalaha cabbiraadda ultrafast waqti-isku-dhafan oo isku-dhafan oo isku-dhafan ilaha iftiinka attosecond iyo terminal cabbirro kala duwan. Tani waxay awood u siin doontaa cilmi-baarayaasha inay sameeyaan attosecond dabacsan ilaa femto-second-waqti-lagu xaliyay cabbirada hababka ultrafast ee arrinta, iyagoo sidoo kale leh xawli iyo xalin booseed. Waxayna u ogolaataa cilmi-baarayaasha inay sahamiyaan oo ay xakameeyaan dhaqdhaqaaqa elektarooniga ah ee ultrafast microscopic ee atamka, molecules, sagxadaha iyo walxaha adag ee badan. Tani waxay aakhirka u gogol xaaraysaa fahamka iyo ku dhaqanka dhacdooyinka macroscopic ee khuseeya dhawr qaybood oo cilmi baadhis ah sida fiisigiska, kimisteriga iyo bayoolaji.

2020, Jaamacadda Huazhong ee Sayniska iyo Tiknoolajiyada waxay soo jeedisay adeegsiga habka-muuqaalka oo dhan si si sax ah loo cabbiro oo dib loogu dhiso garaaca garaaca wadnaha iyadoo loo marayo tikniyoolajiyadda gating indhaha ee inta jeer ee lagu xalliyo. 2020, Akadeemiyada Sayniska ee Shiinaha ayaa sidoo kale sheegtay inay si guul leh u soo saartay garaaca garaaca wadnaha attosecond ee go'doonsan iyada oo qaabaynaysa goobta sawir-qaadista garaaca wadnaha femtosecond iyada oo loo marayo adeegsiga tignoolajiyada albaabka xulashada laba-iftiin. 2023, koox ka socota Jaamacadda Qaranka ee Tiknoolajiyada Difaaca ayaa soo jeediyay hannaan CADEYN degdeg ah, oo loo yaqaan qPROOF, oo loogu talagalay sifada garaaca wadnaha ee go'doonsan ee ultra-wideband.

Sannadkii 2025, cilmi-baarayaal ka socda Akadeemiyada Sayniska Shiinaha ee Shanghai ayaa horumariyay tignoolajiyada isku-darka laysarka oo ku salaysan nidaam waqti-is-waafajin si madax-bannaan u dhisay, taasoo awood u siinaysa cabbirka wakhtiga saxda ah ee saxda ah iyo jawaab-celinta-waqtiga-dhabta ah ee lasers-picosecond. Tani kaliya ma xakameysay joogteynta waqtiga nidaamka ee kala duwanaanshaha attosecond laakiin sidoo kale waxay xoojisay isku halaynta nidaamka laysarka inta lagu jiro hawlgalka muddada dheer. Nidaamka falanqaynta iyo xakamaynta ee la sameeyay ayaa samayn kara hagaajinta wakhtiga dhabta ah ee wakhtiga jitter. Isla sanadkaas, cilmi-baarayaashu waxay sidoo kale adeegsanayeen laysarro is-daba-joog ah oo xoog-leh (STOV).

Goobta laysarka attosecond waxay ku jirtaa xilli horumar degdeg ah, oo daboolaya dhinacyo badan laga bilaabo cilmi-baarista aasaasiga ah ilaa dhiirrigelinta codsiga. Dadaalka kooxaha cilmi-baarista sayniska, dhismaha kaabayaasha, taageerada siyaasadaha qaranka, iyo iskaashiga gudaha iyo caalamiga ah iyo is-weydaarsiga, qaabeynta Shiinaha ee berrinkii lasers atsecond waxay ku raaxaysan doontaa rajooyin horumarineed oo ballaaran. Sida jaamacado badan iyo machadyada cilmi-baarista ku biiraan cilmi-baarista attosecond lasers, koox ka mid ah hibo cilmi-baarista sayniska oo leh aragti caalami ah iyo awood cusub ayaa la kobcin doonaa, kor u qaadida horumarka waara ee attopsecond sayniska. Xarunta weyn ee sayniska ee Attosecond waxay sidoo kale siin doontaa goob cilmi baaris oo hormuud u ah bulshada sayniska waxayna sameyn doontaa wax ku biirinta horumarinta sayniska iyo tignoolajiyada.
