Laser yog lub hauv paus tseem ceeb ntawm cov khoom siv ua laser, qib thev naus laus zis laser tau dhau los ua qhov tseem ceeb uas cuam tshuam rau qib kev ua haujlwm ntawm cov khoom siv ua laser, Suav teb ultrafine laser tau ntsib theem kev siv hauv chaw kuaj mob, theem kev siv hauv kev lag luam me thiab nruab nrab, yuav nkag mus rau theem kev siv loj hauv kev lag luam, theem kev xa khoom lag luam thiab qhov loj ntawm kev lag luam tab tom loj hlob sai nrog kev txhim kho ntawm kev lag luam. Yav tom ntej, nws xav tias qhov loj me ntawm kev lag luam yuav txuas ntxiv loj hlob raws li txoj cai.
Cov ntaub ntawv tseem ceeb ntawm daim ntawv no: tus naj npawb ntawm cov tuam txhab lag luam hauv kev lag luam laser ultrafast, kev xa khoom ntawm ultrafast femtosecond ultrafast laser, qhov loj ntawm kev lag luam laser ultrafast, thiab lwm yam. Ultrafast laser yog hais txog laser nrog lub sijhawm luv dua ntawm laser pulse. Piv nrog nanosecond laser, ultrafast laser pulse lub sijhawm luv heev, lub zog tam sim ntawd siab heev, lub zog tau tsom mus rau thaj chaw me me thiab tsis cuam tshuam los ntawm qhov rov ua dua ntawm lub zog thiab lub zog nruab nrab, qhov zoo ntawm lub teeb yog ruaj khov.
Txij li xyoo 1961, thaum Changchun Institute of Optics thiab Fine Mechanics, Suav Academy of Sciences tsim thawj lub ruby laser hauv Suav teb, cov thev naus laus zis laser tau dhau los ntawm kev txhim kho sai ntawm ntau tshaj 50 xyoo. Hauv kev lag luam, txij li xyoo 1990, cov tuam txhab laser qub tau nkag mus rau hauv kev tsim cov ultra-short pulse laser. Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho tas mus li ntawm kev ruaj khov, laser tau pib siv hauv kev lag luam loj.
Hais txog kev xav tau ntawm kev ua lag luam rau ultrafast laser, raws li cov ntaub ntawv ntawm 2021 Tuam Tshoj Laser Kev Lag Luam Kev Txhim Kho Daim Ntawv Qhia uas tau tshaj tawm los ntawm Wuhan Literature thiab Information Center ntawm Suav Academy of Sciences, Suav Laser Journal, Suav Optical Society thiab lwm lub koom haum, kev xa khoom ntawm ultrafast femtosecond ultrafast laser hauv Suav teb tau nce txhua xyoo txij li xyoo 2015 txog 2020, nrog rau kev loj hlob ntau dua 50%. Xyoo 2020, Tuam Tshoj tau xa 2,100 femtosecond ultra-fast lasers, nce 52.2 feem pua ntawm xyoo.
Hais txog qhov loj ntawm kev ua lag luam, raws li cov ntaub ntawv ntawm Wuhan Literature and Information Center ntawm Chinese Academy of Sciences, qhov muag khoom ntawm Tuam Tshoj lub ultrafast laser tau loj hlob sai sai txij li xyoo 2015 txog 2020. Xyoo 2020, qhov muag khoom ntawm Tuam Tshoj lub ultrafast laser tau tshaj 2.7 billion yuan, nrog rau kev loj hlob txhua xyoo ntawm 10.20%. Qhov nruab nrab txhua xyoo kev loj hlob ntawm kev ua lag luam ultrafast laser txij li xyoo 2015 txog 2020 yog li 56.24%.
Laser yog lub hauv paus tseem ceeb ntawm cov khoom siv ua laser, thiab qib kev txawj ntse ntawm laser dhau los ua qhov tseem ceeb uas cuam tshuam rau qib kev txawj ntse ntawm cov khoom siv ua laser. Lub micro-machining laser yuav ua kom muaj kev hloov pauv ntawm kev txhim kho mus rau qhov kev taw qhia ntawm luv dua wavelength, nqaim dua pulse dav thiab siab dua lub zog, thiab cov xwm txheej ntawm daim ntawv thov ntawm micro-machining yuav raug nthuav dav ntxiv. Daim Ntawv Npaj Tsib Xyoos Thib 14 rau Kev Txhim Kho Kev Lag Luam thiab Kev Sib Raug Zoo hauv Tebchaws thiab Daim Ntawv Qhia Txog Xyoo 2035 Lub Hom Phiaj Pom Kev ntawm Lub Tebchaws Suav, tso tawm thaum Lub Peb Hlis 2021, tau npaj siab los txhawb kev ua kom zoo dua thiab kev sib xyaw ua ke ntawm cov txheej txheem tshiab coj los ntawm cov kev xav tau kev lag luam hauv tebchaws, thiab ua kom nrawm dua kev tsim cov tub rog kev tshawb fawb thiab thev naus laus zis coj los ntawm cov chaw soj nstuam hauv tebchaws. Ib tug xov tooj ntawm cov chaw soj nstuam hauv tebchaws yuav raug teeb tsa los tsom mus rau cov teb tseem ceeb ntawm kev tsim kho tshiab xws li cov ntaub ntawv quantum, photonics thiab micro thiab nano electronics, thiab cov chaw soj nstuam tseem ceeb hauv tebchaws yuav raug tsim dua los tsim ib lub chaw soj nstuam nrog cov qauv tsim nyog thiab kev ua haujlwm zoo.
Tsav los ntawm ob lub log ntawm kev tshawb fawb txog kev tshawb fawb thiab kev nthuav dav ntawm kev thov, lub peev xwm ua lag luam ntawm ultra-short pulse laser uas sawv cev los ntawm picosecond thiab femtosecond yuav txuas ntxiv mus nce. Yog li ntawd, nws tau kwv yees tias qhov loj me ntawm kev lag luam ntawm Tuam Tshoj txoj kev lag luam ultrafast laser yuav tswj hwm tus nqi loj hlob ntawm kwv yees li 15%. Nws tau kwv yees tias qhov loj me ntawm kev lag luam ntawm Tuam Tshoj txoj kev lag luam ultrafast laser yuav ncav cuag li 6.2 billion yuan hauv xyoo 2026.
