Umthombo Ophezulu We-Ultraviolet Wokukhanya

Amasu wokucindezela ngemuva ahlanganiswe nezinkambu ezinemibala emibili akhiqiza umthombo okhanyayo we-ultraviolet
Okwezinhlelo zokusebenza ze-tr-arpes, ukunciphisa i-wavelength yokushayela ngokushayela kanye nokwandisa amathuba okuba yigesi kunezindlela ezisebenzayo zokuthola i-flux ephezulu kanye ne-harmonics ephezulu. Enqubweni yokukhiqiza i-harmonics e-oda eliphakeme ngemvamisa ephezulu yokuphindaphinda, imvamisa ephinda kabili noma indlela ephindwe kabili kathathu yamukelwa ngokufanele ukwandisa ukusebenza kahle kokukhiqizwa kwe-armonics ephezulu. Ngosizo lokucindezela kwe-post-pulse, kulula ukufezekisa ukuncipha kwamandla okuphezulu okudingekayo ukuze kusetshenziswe isizukulwane esiphakeme se-harmonic ngokusebenzisa ukukhanya okufushane kwe-pulse drive, ngakho-ke ukusebenza kahle kokukhiqiza okuphezulu kungatholakala kulokho okwenziwa yi-pulse drive ende.

I-monochroromator ebambekayo i-monochromator ifinyelela ukunxenxeni kokunye ukunxenxa
Ukusetshenziswa kwento eyodwa ehlukile ku-monochromator yethula ushintsho ku-phathelene nokubonaIndlela emisebeni emshadweni we-Ultra-emfushane i-pulse, eyaziwa nangokuthi ishayela phambili litshelwe, okuholela ngesikhathi selula. Isikhathi esiphelele somehluko wendawo yokuphazamiseka nge-wavelecth thavelerth λ kwi-oda le-diffraction oda le-MMλλ, lapho i-N iyisibalo semigqa emile ekhanyayo. Ngokungeza into ehlukile yesibili, i-pulse eqinile ngaphambili ingabuyiselwa, futhi i-monochromator ngokunxephezelwa kokubambezeleka kwesikhathi ingatholakala. Futhi ngokushintsha indlela yokubona phakathi kwezakhi ezimbili ze-monochromator, i-grating pulse shaper ingahle ibekwe ngokwezifiso ukunxephezela ngokunemba lokuhlakazwa okungokwemvelo kwemisebe e-oda eliphakeme. Usebenzisa umklamo wesinxephezelo sokubaleka kwesikhathi, uLucchini et al. Kuboniswe amathuba okukhiqiza nokubonisa amafushane we-monochromatic emfushane ye-monochromatic i-ultraviolet pulses nge-pulse kabanzi ye-5 FS.
Ithimba Lokucwaninga laseCsizmadia esikhungweni sase-Ele Extreg Light Light sathola i-spectrum kanye nokushintshashintsha kwe-monochroul smon-fashion ukuncipha kwe-monochromation ku-suptimition yesikhathi esiphindaphindayo, umugqa ophakeme we-harmonic. Bakhiqiza i-harmonics ephakeme esebenzisa idrayivui-laserNgezinga eliphindaphindwayo le-100 KHZ futhi uzuze ububanzi be-ultraviolet pulth yobubanzi be-4 FS. Lo msebenzi uvula amathuba amasha okuhlolwa isikhathi eside ekutholweni kwe-SITU esikhungweni se-ELPS.

Umthombo ophindaphindwayo ophakeme we-Ultraviolet Light White usetshenziswe kabanzi ekufundeni ama-elektroni ashukumisayo, futhi ukhombise amathemba abanzi wesicelo emkhakheni we-atosecond spectroscopy kanye nokufanekisa microscopic. Ngenqubekela phambili eqhubekayo kanye nokwenziwa okusha kwesayensi nobuchwepheshe, imvamisa ephezulu yokuphindaphinda ngokweqile i-ultravioletUmthombo Okhanyayoiyathuthuka ekuqondisweni kwemvamisa ephakeme yokuphindaphinda, i-Photon Flux ephakeme, i-Photon Energy ephakeme kanye nobubanzi be-pulse elifushane. Esikhathini esizayo, ucwaningo oqhubekayo ngokugcwele okuphindaphindwayo okuningana okwedlulele kwe-ultraviolet light arven kuzothuthukisa ukusetshenziswa kwazo kumandla ashukugesi namanye amasimu okucwaninga. Ngasikhathi sinye, ukusebenza kahle kanye nokulawula ubuchwepheshe bokuphindaphinda okuphezulu okuningana ngokweqile kwe-ultraviolet light field kanye nesicelo sako kumasu wokuhlola afana ne-angular photolectron spectroscopy nayo izogxilwa ekucwaningweni kwesikhathi esizayo. Ngaphezu kwalokho, ubuchwepheshe obunqunyelwe isikhathi sokutholwa kwe-anctroscond Spectroscopy Const Technology kanye nobuchwepheshe besikhathi sangempela se-Microscopic ukucabanga ngokusekelwe kumthombo wokuphindaphinda ngokweqile we-ultraviolet futhi kulindeleke futhi ukuze kufinyelelwe ngokunemba okuxakekile kwesikhathi esinqunyiwe kanye nakwa-nanospace-resolveved emcabangweni ngokuzayo.
