1 、 Kev lag luam hloov pauv nrog lub voj voog tsim khoom hauv lub sijhawm luv luv, thiab kev nkag mus ntev mus txuas ntxiv txhawb kev loj hlob.
(1) Laser kev lag luam saw thiab lwm cov tuam txhab teev npe
Laser kev lag luam saw: Lub sab sauv ntawm lub laser kev lag luam saw yog lub laser chips thiab optoelectronic li ua los ntawm cov ntaub ntawv semiconductor, high-end khoom thiab lwm yam khoom accessories, uas yog lub hauv paus ntawm laser kev lag luam.
Nyob rau hauv nruab nrab ntawm kev lag luam saw, upstream laser chips thiab optoelectronic li, modules, optical Cheebtsam, thiab lwm yam yog siv los tsim thiab muag txhua yam ntawm lasers;Lub downstream yog cov khoom siv laser integrator, nws cov khoom siv thaum kawg siv hauv kev tsim khoom, kev kho mob, kev tshawb fawb, kev siv tsheb, cov ntaub ntawv siv tshuab, kev sib txuas lus kho qhov muag, kho qhov muag thiab ntau lwm yam.
Kev txhim kho keeb kwm ntawm laser kev lag luam:
Xyoo 1917, Einstein tau muab lub tswv yim ntawm kev txhawb zog hluav taws xob, thiab cov tshuab laser maj mam ua kom paub tab hauv kev xav hauv 40 xyoo tom ntej;
Xyoo 1960, thawj ruby laser tau yug los.Tom qab ntawd, txhua yam ntawm lasers tshwm sim ib qho tom qab, thiab kev lag luam nkag mus rau theem ntawm daim ntawv thov nthuav dav;
Tom qab xyoo pua 20th, kev lag luam laser nkag mus rau theem ntawm kev loj hlob sai.Raws li Daim Ntawv Qhia Txog Kev Txhim Kho ntawm Tuam Tshoj Kev Lag Luam Laser, kev lag luam loj ntawm Tuam Tshoj cov khoom siv laser tau nce los ntawm 9.7 billion yuan mus rau 69.2 billion yuan los ntawm 2010 txog 2020, nrog CAGR ntawm kwv yees li 21.7%.
(2) Lub sijhawm luv luv, nws hloov pauv nrog lub voj voog tsim khoom.Nyob rau hauv lub sij hawm ntev, tus nqi nkag tau nce thiab cov ntawv thov tshiab nthuav dav
1. Lub laser kev lag luam yog dav faib downstream thiab fluctuates nrog kev tsim kev lag luam nyob rau hauv lub sij hawm luv luv
Lub sij hawm luv luv ntawm kev lag luam laser muaj feem cuam tshuam nrog kev tsim khoom lag luam.
Qhov kev thov rau cov khoom siv laser los ntawm kev siv peev ntawm cov lag luam hauv qab, uas cuam tshuam los ntawm kev muaj peev xwm thiab kev txaus siab ntawm cov lag luam los siv peev.Cov kev cuam tshuam tshwj xeeb suav nrog cov txiaj ntsig kev lag luam, kev siv peev xwm, kev siv nyiaj txiag sab nraud ntawm cov lag luam, thiab kev cia siab rau yav tom ntej ntawm kev lag luam.
Nyob rau tib lub sijhawm, cov khoom siv laser yog cov cuab yeej siv dav dav, uas yog dav dav hauv tsheb, hlau, roj av, nkoj tsim thiab lwm yam kev lag luam hauv qab dej.Tag nrho txoj kev vam meej ntawm kev lag luam laser muaj feem cuam tshuam nrog kev tsim khoom lag luam.
Los ntawm qhov kev xav ntawm keeb kwm kev hloov pauv hauv kev lag luam, kev lag luam laser tau ntsib ob qhov kev loj hlob tseem ceeb ntawm 2009 txog 2010, Q2, 2017, Q1 txog 2018, feem ntau cuam tshuam nrog kev lag luam kev lag luam thiab qhov kawg ntawm cov khoom lag luam innovation.
Tam sim no, kev lag luam kev lag luam yog nyob rau hauv lub boom theem, kev muag khoom ntawm industrial robots, hlau txiav tshuab cov cuab yeej, thiab lwm yam nyob rau hauv ib tug high theem, thiab kev lag luam laser yog nyob rau hauv ib lub sij hawm ntawm muaj zog thov.
2. Permeability nce thiab daim ntawv thov tshiab nthuav dav hauv lub sijhawm ntev
Laser ua tau pom tseeb qhov zoo hauv kev ua haujlwm zoo thiab kev ua haujlwm zoo, thiab kev hloov pauv thiab kho dua tshiab ntawm kev tsim khoom lag luam txhawb kev txhim kho kev lag luam.Laser ua yog tsom lub laser ntawm cov khoom yuav tsum tau ua, kom cov khoom yuav rhuab, melted los yog vaporized, thiaj li mus cuag lub hom phiaj ua.
Piv nrog rau cov txheej txheem ua ib txwm ua, laser ua muaj peb lub ntsiab zoo:
(1) Txoj kev ua laser tuaj yeem tswj tau los ntawm software;
(2) Lub precision ntawm laser ua yog siab heev;
(3) Laser processing belongs rau kev ua tsis sib cuag, uas tuaj yeem txo qhov poob ntawm cov ntaub ntawv txiav thiab muaj kev ua haujlwm zoo dua.
Laser ua qhia pom tseeb qhov zoo hauv kev ua haujlwm zoo, ua haujlwm ua haujlwm, thiab lwm yam, thiab ua raws li cov lus qhia dav dav ntawm kev tsim khoom ntse.Kev hloov pauv thiab txhim kho kev lag luam kev lag luam txhawb kev hloov kho qhov muag rau kev ua ib txwm ua.
(3) Laser thev naus laus zis thiab kev tsim kho kev lag luam
Laser luminescence txoj cai:
Laser hais txog kev sib koom ua ke, monochromatic thiab coherent directional beam generated los ntawm ib tug nqaim zaus optical kab hluav taws xob los ntawm kev sau cov lus tawm tswv yim resonance thiab hluav taws xob amplification.
Lub laser yog cov cuab yeej tseem ceeb los tsim laser, uas yog tsim los ntawm peb qhov chaw: excitation qhov chaw, ua hauj lwm nruab nrab thiab resonant kab noj hniav.Thaum ua haujlwm, qhov excitation qhov ua rau ntawm qhov nruab nrab ua haujlwm, ua rau feem ntau cov khoom nyob rau hauv lub xeev siab ntawm lub zog siab, tsim cov inversion ntawm particle tooj.Tom qab qhov xwm txheej photon, lub zog siab ntawm cov khoom hloov mus rau qib qis zog, thiab tawm ntau cov photons zoo ib yam li qhov xwm txheej photons.
Photons nrog sib txawv propagation kev taw qhia los ntawm lub transverse axis ntawm lub kab noj hniav yuav khiav tawm ntawm lub kab noj hniav, thaum photons nrog tib txoj kev taw qhia yuav rov qab mus rau hauv cov kab noj hniav, ua rau cov txheej txheem txhawb hluav taws xob txuas ntxiv thiab tsim cov kab teeb laser.
Ua haujlwm nruab nrab:
Kuj hu ua nce nruab nrab, nws hais txog cov khoom siv los paub txog tus lej xov tooj inversion thiab tsim kom muaj hluav taws xob ua kom muaj zog ntawm lub teeb.Qhov nruab nrab ua haujlwm txiav txim siab lub laser wavelength uas lub laser tuaj yeem tawg.Raws li cov duab sib txawv, nws tuaj yeem muab faib ua cov khoom (crystal, iav), roj (atomic gas, ionized gas, molecular gas), semiconductor, kua thiab lwm yam xov xwm.
Pump qhov chaw:
Txhawb nqa qhov nruab nrab ua haujlwm thiab tso cov khoom siv ua haujlwm los ntawm lub xeev hauv av mus rau qib siab zog kom paub txog qhov hloov pauv ntawm tus lej particle.Los ntawm qhov kev xav ntawm lub zog, cov txheej txheem twj tso kua mis yog txheej txheem uas lub ntiaj teb sab nraud muab lub zog (xws li lub teeb, hluav taws xob, chemistry, hluav taws xob hluav taws xob, thiab lwm yam) rau lub particle system.
Nws tuaj yeem muab faib ua optical excitation, gas paug excitation, tshuaj mechanism, nuclear zog excitation, thiab lwm yam.
Resonant kab noj hniav:
Qhov yooj yim tshaj plaws kho qhov muag resonator yog kom tso ob lub iav tsom iav siab ntawm ob qho kawg ntawm qhov nruab nrab nquag, ib qho yog daim iav tag nrho, cuam tshuam tag nrho lub teeb rov qab mus rau nruab nrab rau kev nthuav dav ntxiv;Lwm qhov yog ib feem cuam tshuam thiab ib nrab transmissive reflector raws li daim iav tso zis.Raws li seb tus ciam teb sab tuaj yeem tsis quav ntsej, lub resonator muab faib rau hauv qhov qhib kab noj hniav, kaw kab noj hniav thiab gas waveguide kab noj hniav.
