EyahlukileyoU-Ultraine Laserinxenye yesibini
Ukusasazeka kunye nokusasazeka kokusasazeka: Ukuchithwa kweqela
Omnye wowona mceli mngeni unzima ukudibana naye ohlangatyezwane naye xa usebenzisa i-Unders Wasers igcina ixesha lezipuni ezimfutshane ze-Ultra, ezikhutshwe ngui-laser. Iipuzso ze-ureraisa zichaphazeleka kakhulu kukugqwetha kwexesha, nto leyo eyenza ukuba ihlatywe ixesha elide. Le mpembelelo iba mandundu njengoko ixesha elifutshane lepulse yokuqala. Ngelixa abathengisi be-Underaini banokukhuphela betsala ixesha lemizuzwana engama-50, banokuthi bandwendwe ngexesha lokusebenzisa izibuko kunye neelensi zokudlulisela indawo ekujoliswe kuyo, okanye ukuhambisa ipulse ngomoya.
Eli xesha lokugqwetha lisebenzisa ukusebenzisa umlinganiso obizwa ngokuba kukusasazwa kweqela (i-GDD), ekwabizwa ngokuba yi-odolo yesibini. Ngapha koko, kukwakho nemigaqo yokusasazwa ephakamileyo enokuthi ichaphazele ixesha lokusasazeka kwexesha le-Ultrafart-Laser, kodwa ngokuziqhelanisa, ihlala yanele nje ukuba ihlolisise isiphumo se-GDD. I-GDD yixabiso elixhomekeke rhoqo elixhomekeke kwi-intanethi ngokulinganayo kubungqingqwa bezinto ezinikiweyo. Izinto ezizizo zokuhambisa njengeelensi, iifestile zefestile, kunye nenjongo zihlala zinexabiso elifanelekileyo le-GDD, elibonisa ukuba kanye xa sele icinezele i-pilses yokuhambisa ixesha elide kunaleyo ikhutshiweIinkqubo ze-laser. Izinto ezinamaxesha asezantsi (okt, i-waveength ende) eyadlulayo kunezixhobo eziphezulu (okt, amagqabi amafutshane). Njengoko i-pulse idlula kwimicimbi engaphezulu nangaphezulu, i-wavelengthth kwi-pulse iya kuqhubeka nokwandisa ngakumbi kwaye ngakumbi ngexesha. Ngeemeko ezimfutshane zokuphosa, kwaye ke ngoko ububanzi be-bandwidths, le mpembelelo ithe yagqithisa kwaye inokubangela ukugqwetha kwexesha elibalulekileyo.
Izicelo zoSetyenziso zeLoulraine
spectroscopypypy
Ukusukela ukufika kwemithombo ye-UTrainde, i-spectroscopy yenye yeendawo zabo ezisebenzisa izixhobo. Ngokunciphisa i-pulse ubude kwi-phytosecond okanye iinkqubo ze-attoseconds, iinkqubo ezinamandla kwi-physics, ikhemistri kunye nebhayoloji eyenzekayo ukuba ifezekiswe ngoku. Enye yeenkqubo eziphambili yintshukumo yeatomic, kwaye ukujongwa kwe-Atomic intshukumo kuphucule ukuqonda kwesayensi kwiinkqubo ezisisiseko ezinjengokudluliselwa kwemolekyuli, ukusasazeka kwemolekyuli kunye nokudluliselwa kwamandla kwiiproteni ze-pitosyththotic.
indalo
I-Peak-Amandla Amandla Aserraicers axhasa iinkqubo zokungathobeli kwaye uphucule isisombululo semifanekiso yebhayoloji, enjenge-Pos-microscopy yePEN. Kwinkqubo ye-Poton-Poton, ukuze kuveliswe umqondiso we-nonline kwi-biologium ophakathi okanye kwithagethi ye-Fluorescent, iifoto ezimbini kufuneka zigqithe kwindawo kunye nexesha. Olu hlaso lwangempela luphucula ukucingisisa isisombululo ngokunciphisa imiqondiso yemvelaphi ye-Fluoresces ebuphazamisa izifundo zenkqubo enye ye-photon. Imvelaphi yomqondiso elula iboniswe. Umda omncinci we-microscope ye-Muldipton ikwathintela ifototobocity kwaye inciphise umonakalo kwisampulu.

Ukulungiswa kwempahla ye-laser
Imithombo yolwazi e-Utraine iphinde yaguqula i-Microlisachiness kunye nokuqhubekiswa kwezinto ezibonakalayo ngenxa yendlela ekhethekileyo yokuba i-ulrashort ihla i-istrasses kunye nezinto ezihamba nazo. Njengoko bekutshiwo ngaphambili, xa ukuxoxa nge-LDT, i-Ultraisa i-Ultraisa ihamba ngokukhawuleza kunokuba ixesha lobushushu kwi-lattle. Abaphathi be-Utrainde bavelisa indawo encinci yobushushu kunayeI-Nanosecond yatsala i-lasers, kukhokelela kwilahleko yokuphulukana nendawo kunye nokwehlisa ngakumbi. Lo mgaqo uyasebenza kwizicelo zonyango, apho ukuchaneka kokungalunganga kwe-Ultrafart-i-laser kunceda ukunciphisa umonakalo kwizicubu ezijikelezileyo kwaye kuphucula amava obugulana ngexesha lotyando lase-laser.
I-attosecond ipuse: Ikamva le-ARTRAIDER ASERS
Njengoko uphando luyaqhubeka nokuqhubela phambili abathengi be-Utrainde, imithombo emitsha kunye nephuculweyo yeendawo ezimfutshane zempompo ziyaphuhliswa. Ukufumana ukuqonda kwiinkqubo ezikhawulezayo zomzimba, uninzi lwabaphandi lujolise kwisizukulwana se-aptosecond ipuse-malunga ne-10-18 s kwi-ultraviolet (xuv) i-wavelength yavelela. I-Attosecond ihlelo ivumela ukulandelela intshukumo ye-elektronte kunye nokuphucula ukuqonda kwethu ubume be-elektroniki kunye neendlela zexabiso. Ngelixa ukudityaniswa kwe-Xuv AgtoSomColond Layeliers kwiinkqubo zemveliso kusenokwenza inkqubela phambili enkulu, uphando oluqhubekayo kunye nokuhambela phambili, njengoko bekunjalo nge-phytosencond kunye ne-picosecondImithombo yase-laser.
