Nrog rau kev nthuav dav sai ntawm cov thev naus laus zis thev naus laus zis, ultrafast laser tshwm sim hauv cov neeg' s ob lub qhov muag. Nws muaj qhov tshwj xeeb ultrashort mem tes, super-muaj zog cov yam ntxwv, thiab tuaj yeem muab lub ncov teeb hluav taws xob nrog lub zog qis mem tes. Cov tsos ntawm chirped pulse amplification (CPA) thev naus laus zis kho tau zoo siv ntau ntawm ultrafast laser. Txawv los ntawm cov tsoos ntev-lub ntsej muag laser thiab cov laser nruam, lub ultrafast laser muaj ib qho ultrashort laser mem tes, uas ua rau lub spectrum dav ntawm lub laser mem tes loj heev. Xws li cov khoom siv dav dav muaj cov ntawv thov tseem ceeb hauv kev kawm txog atomic zog qib, laser bonding chemistry, thiab lwm yam. Raws li cov yam ntxwv ntawm ultrafast laser mem tes, peb tuaj yeem siv cov twj tso kua mis-soj ntsuam cov txheej txheem los yees duab kev sib cuam tshuam ntawm laser mem tes thiab teeb meem ntawm lub sijhawm sib txawv, thiaj li yuav tau txais cov yam ntxwv ntawm tag nrho cov txheej txheem. Cov qauv no tau thov rau ntau qhov chaw, xws li hauv kev kawm txog atom thiab molecule cov tshuaj tiv thaiv kev hloov pauv thiab kev soj ntsuam ntawm hluav taws xob cov lus tsa suab, siv femtosecond laser mem tes lossis txawm tias attosecond pulse los soj ntsuam cov txheej txheem tshuaj tiv thaiv los ntawm lub twj tso kua mis-txoj kev soj ntsuam. Thaum lub zog ntom ntom ntom ntom ntawm qhov tsom teeb ultrafast laser ntau tshaj 1012 w / cm 2, hluav taws xob siv hluav taws xob yog qhov loj dua li ntawm cov atom. Nws muab lub zog hluav taws xob muaj zog thiab tsis tshua muaj siab, uas muaj peev xwm dhau qhov khi txoj hlua khi ntawm cov hlua hluav taws xob, ua rau lub zog hluav taws xob ntawm cov lwg me me thiab atoms hloov pauv zoo heev. Los ntawm kev siv cov cuab yeej no, peb tuaj yeem kawm qhov peculiar phenomena sab hauv atom los ntawm ultrafast laser. Tsis tas li ntawd, lub tshuab tso pa ultrafast tseem qhia tau lwm cov yam ntxwv sib txawv, xws li thaj chaw me me thaum tshav kub kub, cov nyhuv muaj peev xwm dhau qhov pom tau qhov sib txawv ntawm qhov tsis txaus thiab cov qhov chaw xaiv ua tau zoo heev.
Kev sib cuam tshuam ntawm ultrafast thiab super mob siab heev laser pulses thiab qhov teeb meem yog ib qho ntawm cov kev tshawb fawb tshaj plaws ntawm cov tam sim no. Nws muaj ntau ntawm cov ntawv thov hauv cov tshiab particle accelerator, ultrafast siab zog lub zog X-ray qhov chaw, thiab lwm yam. Nyob rau tib lub sijhawm, nws muaj ntau lub tswv yim theoretical thiab kev sim tshawb fawb, koom nrog ntau ceg tseem ceeb ntawm physics, xws li laser physics, atomic thiab molecular physics, nonlinear optics, plasma physics, thermodynamics, thiab lwm yam. Nrog cov kev txhim kho txuas ntxiv ntawm kev siv tshuab ultrashort laser pulse, kev siv ntau lub sijhawm ntu ultrashort pulses tau tsim tawm sim, uas muab cov kev sim tsis tau pom dua thiab cov xwm txheej huab lub cev rau txoj kev kawm ntawm kev sib cuam tshuam ntawm teeb thiab teeb meem, Nws tau qhib qhov kev tshawb fawb tshiab ntawm kev sib cuam tshuam ntawm lub teeb thiab teeb meem, tsim cov khoom sib hu ua huab tsis sib haum, zoo heev rau cov ntsiab lus tshawb fawb ntawm optics, thiab nthuav cov kev tshawb fawb ntawm kev sib cuam tshuam ntawm laser thiab ntau yam teeb meem xws li atoms, molecules, ions, electronic cl thiab plasmas kom muaj zog teb ntau ntawm cov kab sib txuam thiab kev sib ze.
Nyob rau hauv kev sib cuam tshuam ntawm ultrafast super mob siab heev laser thiab teeb meem, nrog kev txhim kho tas mus li ntawm kev siv laser, txhua yam ntawm cov khoom siv uas tsis yog hloov zuj zus, xws li kev sib raug zoo ntawm kev sib txuam, threshold ionization, tunneling ionization, thiab lwm yam. Ntxiv mus, lub sij hawm qhov chaw ultrashort laser pulse poob qhov tshwj xeeb ntawm cov yam ntxwv ntawm nthwv dej, uas ua rau muaj kev tshwm sim ntawm lub cev tshiab thiab cov cai. Nws muab cov khoom siv sim tshiab sim rau kev tswj kom zoo, tsis siv hluav taws xob, thiab cov kev tswj hwm ntawm cov khoom siv hluav taws xob tshiab SUBPERIODIC hluav taws xob pob ntawv. Nws tseem muab cov sijhawm ntsuas lub sijhawm tshiab, ntsuas, uas yuav muaj qhov cuam tshuam tseem ceeb rau ntau yam kev qhuab qhia.
Hauv kev pom ntawm kev ua cov khoom, txij li cov tsos ntawm ultrafast laser, vim tias nws lub sijhawm ultrafast thiab lub siab ntawm tus yam ntxwv muaj peev xwm, nws tuaj yeem ceev thiab meej lub zog rau hauv thaj chaw ua haujlwm, thiab paub txog qhov tsis yog kub yaj txias kev kho mob ntawm yuav luag txhua cov ntaub ntawv. Qhov zoo ntawm high precision thiab tsawg kev puas tsuaj uas cov tsoos laser tuaj yeem' t phim tau txais. Cov txiaj ntsig zoo ntawm microsecond laser tau siv dav hauv cov khoom siv microprocessing, nanostructure fabrication, photon pab kiag li lawm, lub siab ntim cia, Kev Kho Mob Bioengineering, thiab lwm yam.
Ultra-vas nthiv laser kev kawm yog qhov tshiab cov tub ntxhais hluas tshiab, uas yog nyob rau Hmo ua ntej ntawm qhov kev sib tawg loj. Xyoo tsis ntev los no, nrog kev sib tawg thiab kev ua lag luam ntawm lub zog loj picosecond, femtosecond laser, thiab cov cuab yeej siv tshuab laser ultrafast laser, lub tshuab laser ultrafast tau hloov los ntawm chav kuaj mus rau kev tsim khoom lag luam thiab daim ntawv thov, dhau los ua cov kev taw qhia kub hauv kev kawm thiab laser daim ntawv thov kev lag luam.
Lub laser ultrafast tuaj yeem daws tau ntau qhov kev ua haujlwm uas nyuaj ua tiav los ntawm cov qauv kev ua haujlwm, xws li siab, meej, ntse, nyuaj, nyuaj, thiab lwm yam, kom ua tiav cov peev xwm tshwj xeeb, kev ua haujlwm zoo thiab kev ua haujlwm zoo, thiab tsim kev lag luam thiab kev tseem ceeb cov txiaj ntsig.
Nrog kev tso tawm thiab kev tsim tawm ntawm" kev lag luam 4. 0" thiab" ua hauv Suav 2025 " nyob rau hauv lub teb chaws Yelemees, qhov kev thov rau kev lag luam siab kawg, kev tsim khoom ntse, thiab cov khoom lag luam siab yuav nce siab yav tom ntej, thiab ultrafast laser thiab advanced micro-nano ua technology yuav ua rau muaj cov hauv kev tshiab rau kev nthuav dav sai. Nws tau kwv yees tias tag nrho cov kev lag luam ntim ntawm lub tshuab ua laser tshaj tawm yuav dhau 1. 5 nphom Asmeskas las los ntawm 2020.
