Kev Lag Luam Laser Nrov Science

I. Kev Taw Qhia Txog Kev Lag Luam Laser

Ua ib tug sawv cev ntawm kev tsim khoom siab heev, cov thev naus laus zis laser tau pom kev loj hlob zoo kawg nkaus hauv kaum xyoo dhau los - Tuam Tshoj txoj kev lag luam laser tau loj hlob los ntawm ib qho kev lag luam tshiab mus rau ib tus neeg ua si loj, nrog rau cov tuam txhab Suav ua tiav kev nthuav dav sai. Saib rau pem hauv ntej rau kaum xyoo tom ntej, Tuam Tshoj txoj kev lag luam laser tau npaj hloov pauv los ntawm "loj" mus rau "zoo" kev loj hlob.

Txij li thaum xyoo pua 20th, laser tau raug qhuas tias yog ib qho ntawm tib neeg txoj kev tsim khoom zoo tshaj plaws, tom qab lub zog atomic, computers, thiab semiconductors. Lub npe hu ua "riam ntse tshaj plaws," "tus ntsuas raug tshaj plaws," "lub teeb ci tshaj plaws," thiab "laser zoo kawg nkaus," nws tau hloov pauv txoj kev siv tshuab niaj hnub no.

II. Keeb Kwm Kev Loj Hlob ntawm Lasers

Txij li xyoo 1916, Albert Einstein tau piav qhia txog kev sib raug zoo ntawm kev tso tawm thiab kev tso tawm ntawm cov atoms, ua rau muaj kev xav txog kev siv lasers los ua kom lub teeb ci ntsa iab. Xyoo 1958, cov kws tshawb fawb Asmeskas tau tawm tswv yim txog lub hauv paus ntsiab lus laser raws li kev soj ntsuam tias lub ntiaj teb tsis tshua muaj siv lead ua los ntawm lub teeb neon tso tawm lub teeb ci ntsa iab, tsom mus rau qhov siab. Lub hauv paus ntsiab lus no hais tias thaum cov khoom raug txhawb nqa los ntawm lub zog sib phim nws qhov zaus oscillation molecular, nws tsim cov teeb ci tsis sib txawv no - laser.

Xyoo 1960, tus kws tshawb fawb Asmeskas Theodore tau tsim lub ntiaj teb thawj lub laser (wavelength: 0.6943 microns) los ntawm kev siv lub teeb ci ntsa iab uas muaj zog heev los ua kom lub pob zeb ruby ci ntsa iab. Lub hom phiaj no tau cim lub laser hloov pauv los ntawm kev tshawb fawb theoretical mus rau kev sim physics. Tom qab ntawd, cov thev naus laus zis laser tau nce qib sai sai thoob plaws ntau qhov chaw, txav mus los ntawm theem sim mus rau kev siv tiag tiag thiab tau txais kev lees paub dav dav ua ib qho ntawm cov khoom tsim tseem ceeb tshaj plaws ntawm lub xyoo pua 20th.

Niaj hnub no, cov khoom siv ua laser uas tau los ntawm cov thev naus laus zis laser tau dhau los ua ib qho cuab yeej tseem ceeb hauv kev tsim khoom lag luam txhua hnub, uas suav nrog cov kev lag luam xws li kev lag luam tub rog, aerospace, automotive manufacturing, kev kho mob, kev tsim khoom siv hluav taws xob, thiab photovoltaic manufacturing.

Nyob rau lub sijhawm dhau los, kev tshawb nrhiav tib neeg hauv thaj chaw laser tau txuas ntxiv mus ua kom tawg cov ciam teb, ua tiav cov txiaj ntsig zoo kawg nkaus. Kev tsim cov lasers hla ntau yam wavelength bands—xws li fiber lasers, CO₂ lasers, ntsuab lasers, xiav lasers, ultraviolet (UV) lasers, ultraviolet tob (DUV) lasers, thiab X-ray lasers—tau muab kev txhawb nqa zoo rau ntau yam kev lag luam, kev kho mob, thiab kev siv hauv kev lag luam. Sib npaug rau kev nce qib ntawm laser wavelengths, kev tsim kho tshiab hauv kev siv laser tau vam meej, xws li laser txiav, laser vuam, laser cim, laser cladding, laser drilling, thiab laser etching.

Nrog kev nce qib ntawm thev naus laus zis tas mus li, cov khoom siv ua laser tau dhau los ua qhov siv tau thiab siv dav. Cov khoom tsim los yog ua los ntawm lasers tau koom ua ke rau hauv tib neeg lub neej txhua hnub, ua ke nrog peb cov kev ua txhua hnub.

III. Kev Txheeb Xyuas Txog Kev Lag Luam Laser

Cov saw hlau lag luam laser muaj peb ntu tseem ceeb:

Upstream: Cov ntaub ntawv thiab cov khoom, suav nrog kev tsim cov khoom siv kho qhov muag, tshuab, kev tswj hwm hluav taws xob, thiab cov khoom siv pneumatic rau cov khoom siv ua laser, nrog rau R&D ntawm cov platform tswj hwm thiab cov software systems.
Nruab Nrab: Kev tsim khoom siv ua laser (qhov tseem ceeb ntawm cov saw hlau kev lag luam).
Cov kev lag luam hauv qab no: Cov kev lag luam thov, suav nrog tsheb, hlau, nkoj tsim, aerospace, khoom siv hluav taws xob rau cov neeg siv khoom, cov ntaub ntawv siab heev, kev ua cov khoom siv semiconductor, kev tsim tshuab, kev kho mob zoo nkauj, thiab kev lag luam hluav taws xob - qhov twg cov thev naus laus zis ua laser tau txais kev siv dav dav.

IV. Kev Lag Luam Laser hauv Suav Teb

Kev Lag Luam Laser: Kev Lag Luam Tuam Tshoj Cov Lag Luam 'Kev Lag Luam Yuav Tsum Tau Txuas Ntxiv Mus Rau Qhov Siab

Vim yog Tuam Tshoj txoj kev loj hlob ntawm kev lag luam thiab kev txhim kho ntawm kev tsim khoom, lub hauv paus kev lag luam muaj zog yuav ua rau muaj kev thov ua lag luam rau kev tsim khoom laser thiab tsim cov xwm txheej zoo rau kev tsim kho tshiab hauv kev lag luam. Saib rau pem hauv ntej, kev lag luam khoom siv laser ntawm Tuam Tshoj muaj peev xwm loj hlob ntawm kev lag luam.

Nrog rau qhov kev thov nce ntxiv hauv kev txiav / vuam fais fab siab, kev ua cov khoom siv hluav taws xob me me, thiab kev ntsuas, qhov kev thov rau cov khoom siv laser hauv kev lag luam yuav tsum tswj hwm kev loj hlob ruaj khov. Tam sim no, qhov kev thov ua lag luam hauv kev lag luam ua cov khoom siv tab tom loj hlob sai, thaum tus nqi nkag mus ntawm cov tshuab laser tseem qis. Thaum cov thev naus laus zis ua cov khoom siv laser loj hlob thiab kev ua haujlwm zoo dua, qhov kev cia siab rau qhov kev thov rau cov khoom siv laser hauv kev lag luam muaj kev cia siab heev.
