I. Cov Ntsiab Cai Txuj Ci thiab Qhov Zoo
Lub hauv paus ntawm lub laser disk nyob rau hauv nws qhov nce nruab nrab -ib lub disk- zoo li tus siv lead ua (xws li Yb:YAG) uas feem ntau tsuas yog li 0.1 millimeters tuab. Cov qauv geometric nyias nyias no tso cai rau cov cua sov ua kom nrawm nrawm rau hauv lub dab dej kub ntawm sab nraub qaum, kom tsis txhob "thermal lensing effect" tshwm sim los ntawm qhov tsis sib xws ntawm qhov kub thiab txias hauv cov pas nrig lasers, yog li ua kom cov nqaj zoo. Hauv ultra- daim ntawv thov laser ceev, disk lasers tuaj yeem ua vuam, drilling, thiab txiav nrog micrometer- qib precision. Qhov tsawg kawg nkaus kub cuam tshuam thaum ua tiav qhov hu ua "txias ua."
II. Txiav -Txoj kev tshawb fawb thiab kev ua tau zoo
Hauv kev tshawb fawb tshawb fawb, ultra-fast disk lasers yog cov tsav tsheb zoo tshaj plaws rau kev tsim cov pulses attosecond pulses thiab siab -flux huab ultraviolet (XUV) qhov chaw. Nyob rau hauv xyoo tas los no, pab pawg tshawb fawb hauv tsev thiab thoob ntiaj teb tau rov tsim cov ntaub ntawv tshiab hauv kev nce lawv lub zog nruab nrab thiab lub zog mem tes. Piv txwv li, qee pawg tau ua tiav ntau dua 200 mJ ntawm picosecond laser tso zis ntawm 1 kHz rov ua dua tus nqi los ntawm cov txheej txheem ua kua dej txias thiab ntau- dhau cov qauv twj tso kua mis. Lwm qhov kev tshawb fawb tau teeb tsa cov ntaub ntawv oscillator tshiab ntawm 550 watts ntawm nruab nrab lub zog siv daim iav tshwj xeeb arrays thiab semiconductor saturable absorber mirrors (SESAM). Cov siab -repetition{11}} tus nqi, siab -zog ultra- laser tshuab ceev ceev muab lub teeb muaj zog rau kev txiav- ntug kev tshawb fawb hauv attosecond physics, laser xob laim rods, thiab nto photoelectron dynamics.
III. Core Industrial Application Scenarios
Hauv kev tsim khoom lag luam, ultra-fast disk lasers tau txhawb nqa ntau yam kev lag luam tawm tswv yim:
Tshiab Zog thiab Automotive Manufacturing: Nyob rau hauv lub tsheb fais fab (EV) sector, disk lasers yog dav siv rau cov roj teeb kev twb kev txuas welding ntawm cov ntaub ntawv zoo li tooj liab thiab txhuas. Lub zog sib koom ua ke tuaj yeem ncav cuag 95% ntawm cov khoom siv hauv paus yam tsis muaj spatter, zoo kawg nkaus yoog mus rau qhov ua tiav ntawm cov kua txias txias thiab tooj liab busbars.
Aerospace: Lawv yog siv los laum qhov txias txias hauv npib tsib xee-raws li superalloy turbine hniav, txhim kho kev ua tau zoo ntawm cov tshuab aero thiab txhawb kev tsim khoom ntawm - tiam tom ntej airframe qauv.
Semiconductors thiab Cov Khoom Tshiab: Siab-lub zog UV nanosecond disk lasers tuaj yeem txhawb cov txheej txheem tseem ceeb xws li laser nqa-tawm (LLO) thiab excimer laser annealing (ELA), pab kev ua tiav ntawm OLED panels thiab semiconductor wafers. Tsis tas li ntawd, lawv ua haujlwm tseem ceeb rau lwm txoj hauv kev siv thev naus laus zis rau - tiam EUV lithography teeb qhov chaw.
Cov khoom siv tshwj xeeb thiab cov cuab yeej kho mob: Lawv pab ua kom muaj txiaj ntsig zoo ntawm cov pa roj carbon fiber ntau -cov khoom siv hluav taws xob ntxiv (CFRP) nrog kev puas tsuaj thermal tsis zoo. Hauv kev kho mob, lawv tau siv los tsim cov coronary stents nrog sub-50-micron nta, txhim kho biocompatibility.
IV. Industrialization txheej txheem thiab kev ua lag luam toj roob hauv pes
Lub ntiaj teb no ultra-fast disk laser kev lag luam tab tom muaj kev loj hlob sai thiab npaj kom ncav cuag ze li ntawm $ 700 lab los ntawm 2029. Rau lub sijhawm ntev, cov thev naus laus zis tseem ceeb hauv daim teb no tau raug monopolized los ntawm cov tuam txhab txawv teb chaws, xws li hauv lub teb chaws Yelemees. Txawm li cas los xij, nyob rau xyoo tas los no, Suav cov lag luam tau nrawm lawv cov kev ua tiav hauv cov haujlwm no. Cov tuam txhab lag luam hauv tsev zoo li Suzhou Zhonghui Laser tau ua tiav cov tub ntxhais disk laser thev naus laus zis thiab ua tiav cov khoom lag luam loj. Lawv tau tso tawm kilowatt-theem femtosecond lasers thiab siab-lub zog UV thiab ntsuab laser platforms. Cov kev nce qib no tsis tau tsuas yog ua tiav ntau pua lab ntawm RMB hauv cov nqi tso tawm hauv kev lag luam precision tab sis kuj tau muab kev ywj pheej thiab tswj tau lub teeb pom kev zoo rau cov phiaj xwm loj hauv teb chaws xws li cov khoom siv hluav taws xob EUV thiab kev tswj hwm nuclear fusion. Saib ua ntej, nrog rau kev nce qib hauv kev sib xyaw thiab kev tsim qauv ntawm fiber ntau lasers, daim ntawv thov pib rau disk lasers yuav raug txo qis ntxiv, ua rau muaj kev loj hlob dav dav.
