Laser na-anya ụgbọala na-ekpebi oke elu nke isi iyi ọkụ laser attosecond

Laser na-anya ụgbọala na-ekpebi oke elu nkelaser attosekọndisi iyi ìhè.
Ugbu a,lasers attosecond pulsea na-emepụtakarị site na mmepụta harmonic dị elu (HHG) nke ubi siri ike na-akwali. A pụrụ ịghọta ihe dị mkpa nke mmepụta ha dị ka elektrọn ndị a na-eme ka ha dị ka ion, na-eme ngwa ngwa, ma na-ejikọta ọzọ iji wepụta ike, si otú a na-ewepụta attosecond XUV pulses.
Ya mere, mmepụta nke attosecond pulses na-enwe mmetụta dị ukwuu na obosara pulse, ike, ogologo ebili mmiri, na ugboro ugboro nke laser na-anya ụgbọala: obosara pulse dị mkpụmkpụ na-enyere aka ikewapụ attosecond pulses, ike dị elu na-eme ka ionization na arụmọrụ dịkwuo mma, ogologo ebili mmiri na-eme ka ike mbepụ dịkwuo elu mana ọ na-ebelata arụmọrụ ntụgharị nke ukwuu, na ugboro ugboro ugboro na-eme ka oke mgbaàmà-na-mkpọtụ dịkwuo mma mana ike otu-pulse na-ejedebe.
Ngwa dị iche iche na-elekwasị anya na ihe ngosi dị iche iche nke laser attosecond, si otú a dabara na nhọrọ nhazi nke ụdị ịnya ụgbọala dị iche icheisi mmalite laser.
Maka ngwa dịka nyocha ultrafast dynamics na electron microscopy, stable isolation of attosecond pulses (IAP) na-achọkarị mkpụmkpụ-pulse driving pulses na njikwa dị mma nke carrier envelopu phase (CEP) iji nweta irè oge gating na ebili mmiri controllability;
Maka nnwale dịka pump-probe spectroscopy na multi-photon ionization, attosecond radieshon ike dị elu ma ọ bụ nke dị elu na-enyere aka melite arụmọrụ mkpali/ntinye, nke a na-enwetakarị n'okpuru ike ịnya ụgbọ elu dị elu na ọnọdụ ike dị elu site na HHG, ma chọọ ịnọgide na-enwe nhazi oge a na-anabata na ịdị mma nke ionization dị elu;
Iji mepụta radieshọn attosecond na windo X-ray (nke bara uru nke ukwuu maka onyonyo coherent na X-ray absorption spectroscopy nke edoziri oge), a na-ejikarị draịva ogologo-wavelength mid-infrared eme ihe iji mee ka ike harmonic cutoff dịkwuo elu ma nweta mkpuchi ike photon dị elu;
N'ihe atụ ndị na-emetụta izi ezi nke ọnụọgụgụ, dịka ịgụta na fotoelectron spectroscopy, ugboro ugboro ugboro dị elu nwere ike ime ka oke mgbaàmà-na-mkpọtụ na arụmọrụ inweta data ka mma nke ukwuu, ebe obere chajị/ike otu-pulse na-enyere aka belata mmachi nke mmetụta chajị oghere na mkpebi ike.
E gosiri njikọ dị n'etiti paramita laser driving, njirimara laser pulse attosecond, na ihe achọrọ maka ngwa na Foto 1. N'ozuzu, ihe achọrọ nke ngwa na-akwalite mmezi nke paramita laser pulse attosecond na-aga n'ihu, si otú a na-akwalite mmepe na-aga n'ihu nke usoro ihe owuwu na teknụzụ dị mkpa nkelaser dị oke ọsọsistemụ.
