Femtosecond Laser Daim Ntawv Thov hauv Peb Qhov Tseem Ceeb
Aug 21, 2023
Txij li thaum nws cov invention, lub laser tau dav siv nyob rau hauv ntau yam xws li ua thiab manufacturing, kuaj, thiab kev kho mob ntawm nws monochromaticity, zoo directionality, thiab concentration ntawm lub zog, ntawm ntau lwm yam zoo. Nyob rau hauv xyoo tas los no, cov kws tshawb fawb tau tshawb fawb thiab nrhiav pom ib lub laser peculiar ntau dua - femtosecond laser. Nws tau tshaj tawm tias femtosecond laser yog lub tshuab pulse luv tshaj plaws, uas txhais tau hais tias tib neeg tuaj yeem tau txais nws hauv chav kuaj mob. Femtosecond laser, nyob rau hauv ib tug sib cais thib ob, muab lub hwj chim tshaj lub ntiaj teb no lub zog tag nrho ntawm hluav taws xob tsim; Cov kws tshawb fawb tau kwv yees tias femtosecond laser yuav ua lub luag haujlwm tseem ceeb hauv thaj chaw ntawm lub zog tshiab nyob rau xyoo tom ntej.
Ultra-ceev thiab ultra-muaj zog laser tsuas yog siv femtosecond laser ua lub hauv paus ntawm kev tshawb fawb thiab daim ntawv thov. Raws li cov cuab yeej tshawb fawb tshwj xeeb thiab txhais tau tias, daim ntawv thov ntawm femtosecond laser tuaj yeem muab sau ua peb yam tseem ceeb, uas yog, daim ntawv thov ntawm femtosecond laser hauv thaj tsam ntawm ultra-ceev, daim ntawv thov ntawm ultra-muaj zog thiab daim ntawv thov ntawm ultra-fine. precision machining.
Ultrafast phenomena yog xa mus rau lub cev, tshuaj, los yog cov txheej txheem lom neeg uas tshwm sim nyob rau hauv lub microscopic system ntawm teeb meem nrog ceev hloov. Femtosecond laser nyob rau hauv ultrafast phenomenon kev tshawb fawb plays ib tug ceev txheej txheem kuaj mob. Lub femtosecond laser zoo li lub moos zoo nkauj thiab ultra-high-speed "lub koob yees duab," uas tuaj yeem txheeb xyuas thiab sau qee cov txheej txheem ceev hauv cov xwm txheej, tshwj xeeb tshaj yog nyob rau theem atomic thiab molecular. Hauv daim teb no, lub femtosecond laser qhib lub qhov rooj tshiab, cia peb pom lub ntiaj teb hloov maj mam dua.
Daim ntawv thov ntawm femtosecond lasers nyob rau hauv ultra-kev siv (tseem hu ua muaj zog-field physics) yog vim lub fact tias lub ncov lub hwj chim thiab kev siv ntawm femtosecond pulses nrog lub zog tshwj xeeb yuav ua tau siab heev. Lub tshuab hluav taws xob sib txuas nrog lub teeb ci zoo li no tuaj yeem loj dua li Coulomb teb nyob rau hauv ib lub atom, yog li sai sai stripping feem ntawm tag nrho nws cov electrons. Yog li ntawd, femtosecond lasers yog qhov tseem ceeb rau kev kawm siab-order nonlinear multiphoton txheej txheem hauv atomic thiab molecular systems. Lub zog densities sib xws rau femtosecond lasers tsuas yog ua tau hauv nuclear tawg. Femtosecond khaus lub teeb tuaj yeem tsim cov X-rays thiab lwm yam luv luv wavelengths ntawm lub teeb, uas tuaj yeem siv los kawm txog kev tswj hwm nuclear fusion.
Nrog rau qhov loj me ntawm kev sib xyaw ua ke, cov khoom siv hluav taws xob tau dhau los ua qhov me thiab me me, thiab qhov kev thov rau qhov no muab chav rau ultrafine ua technology. Femtosecond laser rau kev ua ultrafine yog femtosecond laser rau ultrafast phenomenon kev tshawb fawb thiab ultra-ntse phenomenon kev tshawb fawb, ntxiv rau lwm daim ntawv thov tseem ceeb ntawm femtosecond laser technology tshawb fawb teb. Daim ntawv thov no tau maj mam tsim nyob rau hauv xyoo tas los no los teb rau cov kev xav tau ntawm kev lag luam, thiab kev vam meej tseem ceeb tau ua tiav.
Lub femtosecond ultrafast thiab femtosecond ultra-ntse kev tshawb fawb txawv ntawm femtosecond laser ultrafine ua, thiab advanced manufacturing technology yog ze ze rau kev tsim tshwj xeeb kev lag luam ntau lawm technology uas muaj peev xwm ua si lub luag hauj lwm ncaj qha nyob rau hauv txhawb. Femtosecond laser ultrafine ua yog niaj hnub ntiaj teb no ntawm lasers optoelectronics kev lag luam, ib tug incredibly yuam kev txiav-ntug kev tshawb fawb kev taw qhia. Nrog rau kev txhim kho txuas ntxiv ntawm femtosecond laser thev naus laus zis thiab kev nthuav dav tsis tu ncua ntawm daim teb ntawm daim ntawv thov, femtosecond laser yuav undoubtedly muaj ntau daim ntawv thov.
