Nrog rau kev txhim kho tas mus li thiab kev loj hlob ntawm laser technology, lasers tau dav siv nyob rau hauv high-end manufacturing, ntaub ntawv thiab kev sib txuas lus, lom thiab kev kho mob thiab kev noj qab haus huv industries, tub rog kev lag luam, lub teb chaws tiv thaiv thiab kev ruaj ntseg thiab lwm yam kev lag luam. Nws yog ib qho ntawm cov cuab yeej tseem ceeb rau kev sib tw high-tech hauv ntiaj teb niaj hnub no. Ua ntej, ntau thiab ntau cov kev lag luam ib txwm cia siab rau laser ua tshuab los txhim kho kev ua tau zoo ntawm cov khoom, daws cov teeb meem uas tsis tuaj yeem daws tau los ntawm cov txheej txheem ua thiab cov txheej txheem, thiab ua tiav qhov kev hloov pauv. Ntau lub teb chaws tsim kho kuj suav nrog kev txhim kho ntawm laser technology raws li lawv lub teb chaws qhov tseem ceeb hauv cheeb tsam thiab muab kev txhawb zog.
Ua raws li cov roj ntsha ib txwm muaj thiab cov khoom lag luam lasers, qhov tshwm sim thiab kev loj hlob sai ntawm cov lasers tshiab xws li fiber ntau lasers, semiconductor lasers, thiab ultrashort pulse lasers yuav pom tseeb coj cov cib fim tshiab thiab cov teeb meem rau kev lag luam thiab kev tsim khoom. Tsis ntev los no, tus neeg sau xov xwm xam phaj Zhang Ke, tus kws tshaj lij hauv kev lag luam optoelectronics hauv Suav teb thiab CTO ntawm Grayson Industrial Co., Ltd., los qhia txog daim ntawv thov thiab kev cia siab ntawm cov thev naus laus zis tshaj plaws ultrafast lasers hauv kev lag luam tsim khoom. .
Tus neeg sau xov xwm: Nws tsis yog txog thaum xyoo 1990 uas muaj ntau yam tunable ultrashort mem tes lasers ua tiav qhov kev hloov pauv los ntawm cov chaw soj ntsuam tshawb fawb mus rau kev ua lag luam, thiab tau siv dav hauv ntau qhov chaw. Raws li ib tug hluas tshiab kev qhuab qhia, kev loj hlob ceev ntawm ultrafast lasers yog amazing. Kev cog qoob loo ntawm optoelectronics rau ze li kaum xyoo, koj puas xav qhia qhov kev vam meej tshiab hauv kev tshawb fawb thiab kev loj hlob ntawm ultrafast laser technology?
Zhang Ke: Ua raws li kev pib thiab kev loj hlob ntawm German "Industry 4.0" thiab "Ua hauv Tuam Tshoj 2025", qhov kev thov rau high-end manufacturing, ntse tsim, thiab high-precision manufacturing yuav nce siab nyob rau hauv yav tom ntej. Kev sib xyaw ua ke yog qhov kev taw qhia kub kawg hauv kev kawm thiab kev lag luam laser. Txawm li cas los xij, micro-nano fabrication ntawm ultrafast lasers yog ib qho kev txiav-ntug interspersed kawm qeb, uas suav nrog kev siv tshuab, kho qhov muag, physics, chemistry, cov ntaub ntawv, thiab lwm yam, thiab tau siv dav hauv kev tiv thaiv hauv tebchaws, biology. , ntaub ntawv, khoom siv kho mob, thiab tsheb. Nyob rau hauv lwm yam lus, lub ultrafast laser technology nyob rau hauv lub neej yav tom ntej yuav koom nyob rau hauv ntau kev qhuab qhia. Siv lub laser ultra-ceev ceev nrog mem tes dav luv dua 10ps ({10}}s) ua piv txwv. Nws muaj qhov peculiar zoo ntawm ultra-muaj zog thiab ultra-ceev, uas ua rau cov txheej txheem ntau lawm zoo li lub sij hawm thiab lub zog siab tshaj plaws, ua microstructure processing Qhov precision tau zoo heev, uas muaj lub zog loj loj rau kev nce qib ntawm ntau yam kev qhuab qhia thiab kev ua tiav hauv high-tech.
Tus neeg sau xov xwm: Koj thiab koj pab neeg Grayson kuj muaj kev tshawb fawb tob hauv thaj tsam ntawm ultrafast laser technology. Puas muaj kev tawg tau ua rau tam sim no?
Zhang Ke: Lub laser tsim los ntawm Grayson pab neeg ua tau yog ib tug high-stability full-band ultrafast laser, uas combines fiber ntau laser thiab ultrafast laser tshuab, nrog rau ultrafast fiber lasers nrog wavelengths ntawm 1 micron, 1.5 micron thiab 2 micron. Tsom ntsoov rau thaj chaw micron-teev, nws muaj lub zog siab tshaj plaws thiab ultra-luv mem tes dav, uas tsis yog tsuas yog ua kom tsis txhob muaj cua sov hloov thiab thermal diffusion hauv cov txheej txheem ua, tab sis kuj tseem paub txog kev ua laser "txias" tiag tiag, thaum txhim kho. Txhawm rau txhim kho qhov tseeb ntawm micromachining, nws tau ua tiav kev koom tes nrog ntau qhov kev lag luam. Piv txwv li, nyob rau hauv kev koom tes nrog microelectronics technology, nws loj-scale integrated circuits yog ua ntau miniaturized kom tau raws li kev siv ceev ceev thiab muaj zog ua hauj lwm yuav tsum tau; thiab nyob rau hauv aerospace, precision machinery, biomedicine thiab lwm yam kev lag luam, nws precision processing muaj peev xwm kuj muaj ib tug ntau yam ntawm daim ntawv thov ntawm lub zog. Tam sim no, cov ntaub ntawv sib txawv ntawm ultra-ceev laser micro-nano ntau lawm tau txais kev saib xyuas los ntawm txhua lub teb chaws thiab dhau los ua "kev nyiam tshiab" ntawm lub sijhawm.
Reporter: Yuav ua li cas koj twv seb yav tom ntej txoj kev loj hlob qauv ntawm ultrafast lasers?
Zhang Ke: Nyob rau hauv daim ntawv thov teb, ntau sophisticated ua thiab digital transformation yog lub hom phiaj ntawm txoj kev loj hlob. Thawj yog kom txo qis ntau lawm thiab nce peev los tsim me me ultra-ceev lasers thiab micro-processing systems los txhim kho qhov chaw ua haujlwm thiab ua kom lub neej ntev ntawm lub tshuab. Qhov thib ob yog tsim qauv tsim software rau laser ua cov yam ntxwv thiab ua cov ntaub ntawv, thiab siv cov ntaub ntawv loj technology los txhim kho cov txheej txheem yog simulated kom paub qhov zoo tshaj plaws parameter ua. Los ntawm qhov kev xav ntawm kev kawm, kev txhim kho ntawm kev ua tiav theoretical piav qhia thiab kev tshawb pom ntawm lub cev ntawm kev sib cuam tshuam ntawm laser thiab teeb meem hauv cov xwm txheej hnyav yuav dhau los ua lub hauv paus tseem ceeb rau kev txhim kho txuas ntxiv ntawm laser technology.
