Laser-ka wadista ayaa go'aamiya xadka sare ee isha iftiinka laysarka ee attosecond

Laser-ka wadista ayaa go'aamiya xadka sare eelaysarka attosecondilo iftiin.
Waqtigan xaadirka ah,laser-ka garaaca wadnaha ee attosecondwaxaa inta badan laga sameeyaa jiil heer sare ah oo iswaafajin ah (HHG) oo ay wadaan goobo xooggan. Nuxurka jiilkooda waxaa loo fahmi karaa sida elektaroono la ioneeyay, la dardargeliyay, iyo dib-u-isku-darka si loo sii daayo tamarta, taasoo soo saaraysa garaaca XUV ee attosecond.
Sidaa darteed, wax soo saarka garaaca attosecond waa mid aad u xasaasi ah ballaca garaaca, tamarta, hirarka, iyo soo noqnoqoshada ku celcelinta ee laysarka wadista: ballaca garaaca gaaban ayaa ku habboon in la kala saaro garaaca attosecond, tamar sare waxay hagaajisaa ionization iyo hufnaanta, hirarka dheer waxay kor u qaadaan tamarta goynta laakiin si weyn ayay u yareeyaan hufnaanta beddelka, iyo soo noqnoqoshada ku celcelinta sare waxay hagaajisaa saamiga calaamadda-ilaa-sawaxanka laakiin waxaa xaddidaya tamarta hal-garaaca.
Codsiyada kala duwan waxay diiradda saaraan tilmaamayaasha muhiimka ah ee kala duwan ee laysarka attosecond, sidaas darteed waxay u dhigantaa xulashooyinka naqshadeynta noocyada kala duwan ee wadistaIlo laysar ah.
Codsiyada sida cilmi-baarista firfircoonida ee aadka u dheereysa iyo mikroskoobka elektaroonigga ah, go'doominta xasilloon ee garaaca attosecond (IAP) badanaa waxay u baahan tahay garaaca wadnaha oo gaaban iyo xakamaynta wejiga baqshadda side ee wanaagsan (CEP) si loo gaaro waqti wax ku ool ah iyo xakamaynta qaabka hirarka;
Tijaabooyinka sida bamka-baaritaanka spectroscopy iyo ionization-ka badan ee photon, shucaaca attosecond-ka sare ama qulqulka sare wuxuu ka caawiyaa hagaajinta hufnaanta kicinta/nuugista, taas oo badanaa lagu gaaro tamar sare oo wadista ah iyo xaaladaha awoodda celceliska sare iyada oo loo marayo HHG, waxayna u baahan tahay ilaalinta isku-dhafka wejiga la aqbali karo iyo tayada faybarka marka la eego xaaladaha ionization-ka sare;
Si loo abuuro shucaaca attosecond ee daaqadda X-ray (kaas oo qiimo weyn u leh sawir-qaadista isku-dhafan iyo spectroscopy-ga nuugista raajada X-ray ee waqtiga lagu xalliyay), wadista hirarka-dheer ee dhexe ee infrared-ka ayaa badanaa loo isticmaalaa in lagu kordhiyo tamarta goynta iswaafajinta iyo in la helo daboolida tamarta photon-ka oo sareysa;
Cabbiraadaha xasaasiga u ah saxnaanta tirakoobka, sida tirinta iyo sawir-qaadista sawir-qaadista, soo noqnoqoshada soo noqnoqoshada sare waxay si weyn u horumarin kartaa saamiga calaamadda-ilaa-sawaxanka iyo hufnaanta helitaanka xogta, halka dallacaadda/tamarta hal-garaac oo hooseeya ay gacan ka geysaneyso yaraynta xaddidaadda saameynta dallacaadda booska ee xallinta kala-soocidda tamarta.
Iswaafajinta u dhaxaysa xuduudaha laysarka wadista, astaamaha laysarka garaaca wadnaha ee attosecond, iyo shuruudaha codsiga waxaa lagu muujiyay Jaantuska 1. Guud ahaan, baahida codsiyada ayaa si joogto ah u horseedda horumarinta dheeraadka ah ee xuduudaha laysarka garaaca wadnaha ee attosecond, sidaas darteedna waxay horseedaa horumarinta joogtada ah ee qaab-dhismeedka iyo teknoolojiyada muhiimka ah eelaysar aad u dhakhso badannidaamyada.
