Lub 25th Tuam Tshoj International Hi-Tech Fair tau pib nag hmo, thiab cov kev siv technology tshiab ua tiav hauv ntau qhov kev lag luam tau nthuav tawm. Shenzhen University of Technology, ib tug loj tus naj npawb ntawm high-precision "dub science thiab technology" khoom kuj yog nyob rau hauv cov zaub, tag nrho cov qhia lub tsev kawm ntawv cov kws qhia ntawv thiab cov tub ntxhais kawm tsom mus rau kev txawj ntse txawj ntse, cov ntaub ntawv tshiab technology, ntse kho mob, Internet ntawm tej yam, lub zog cia. roj teeb thiab lwm yam tseem ceeb ntawm kev lag luam, ntxiv dag zog rau kev koom tes ntawm kev lag luam, kev kawm thiab kev tshawb fawb, thiab txhawb nqa cov txiaj ntsig zoo ntawm kev tshawb fawb thiab thev naus laus zis.
Thaum Lub Kaum Ib Hlis 16, Ruan Shuangchen, Thawj Tswj Hwm ntawm Shenzhen University of Technology, tuaj rau lub tsev kawm ntawv lub rooj muag khoom, tau soj ntsuam cov txiaj ntsig ntawm lub tsev kawm ntawv cov khoom pov thawj ib los ntawm ib qho, thiab ua tib zoo nug txog cov xwm txheej tam sim no ntawm txoj haujlwm tshawb fawb, cov ntsiab lus ntawm kev tsim kho tshiab thiab nws daim ntawv thov. , nws txhawb cov kws tshawb fawb kom ua rau muaj kev mob siab rau txhawm rau ua kom muaj kev lag luam ntawm kev tshawb fawb tshawb fawb, thiab muab cov kev xav tau siab dua rau kev hloov pauv thiab kev siv lub tsev kawm ntawv qib siab thiab cov txiaj ntsig tshiab.
At the same time, new good news came from the university's scientific research work. Recently, the national key research and development project team led by Prof. Ruan Shuangchen of Shenzhen University of Technology, under the support of the project of "Crystal Thin Wafer Processing and Preparation of New Generation of Gain Devices" of the National Key Research and Development Program of the Ministry of Science and Technology, has made important progress in research on the key scientific issues of crystal thin wafer processing and preparation of new generation of gain devices, and is the first one to realize the breakthrough of We are the first one in China to realize the crystal package of Yb:YAG wafer with diameter >20mm, thiab tsim lub 48-stroke pumping system ntawm kilowatt chav kawm.
High-power ultrafast lasers yog siv nyob rau hauv advanced manufacturing, cov ntaub ntawv, microelectronics, kev kho mob, zog, tub rog thiab lwm yam kev lag luam, thiab muaj feem xyuam rau kev tshawb fawb thiab thev naus laus zis yog qhov tseem ceeb los txhawb txoj kev loj hlob ntawm lub teb chaws cov tswv yim. Laser nce ntaus ntawv yog cov khoom siv tseem ceeb ntawm lub zog siab ultrafast laser, uas tau txhawj xeeb heev los ntawm txhua lub teb chaws hauv ntiaj teb. Nyias-zaj duab xis lasers nrog cov nqaj zoo heev thiab kev ua haujlwm siab ntawm kev hloov kho qhov muag-rau-kho qhov muag tau siv dav hauv ntau qhov chaw xws li kev tsim khoom lag luam thiab kev tshawb fawb yooj yim. Txawm li cas los xij, qhov tsis muaj cov thev naus laus zis tseem ceeb xws li kev ua tiav ntawm cov yeeb yaj kiab nyias nyias, tsim thiab ntim cov tshuab hluav taws xob, thiab kev npaj cov cuab yeej nce qib tau txwv tsis pub muaj kev txhim kho ntxiv ntawm lub zog nyias-zaj duab xis lasers hauv Suav teb.
Relying ntawm Lub Chaw Haujlwm Tseem Ceeb ntawm Advanced Optical Precision Manufacturing Technology rau Guangdong Universities, Shenzhen Key Laboratory of Laser Engineering, Sino-German Institute of Intelligent Manufacturing, thiab College of Engineering Physics, Shenzhen University of Technology tau ua tiav cov kev tshawb fawb ntawm nyias-flake. laser thev naus laus zis txij li xyoo 2021, thiab tau txais nws tus kheej tsim cov pob zeb nyias nyias nrog ib txoj kab uas hla ntawm 12 hli thiab cov cuab yeej siv hluav taws xob rov ua kom zoo dua thaum pib ntawm 2022 kom paub txog lub zog loj regenerative amplification ntawm lub resonance kab noj hniav los ntawm chromatic dispersion them nyiaj thiab los ntawm kev tswj. Kev them nyiaj dispersion thiab cov nyhuv nonlinear ntawm lub zog loj regenerative amplification resonant kab noj hniav, lub laser tso zis ntawm tib lub zog pulse ＞ 500μJ, mem tes dav 7.5ps, nruab nrab lub zog ＞ 200W yog pom tau, tshwj xeeb tshaj yog kev ua tau zoo ntawm nqaj zoo M2＜1.1 thiab optical-rau-optical conversion efficiency ＞ 50%, uas nteg lub hauv paus ruaj khov rau qhov zoo nonlinear zaus hloov dua siab tshiab sab nraum cov kab noj hniav.
The project team adopted wavelength-locked 969nm "zero-phonon line" pumping to realize the highest continuous output power >1300W, qhov siab tshaj plaws optical-rau-optical conversion efficiency ntawm ze li ntawm 80%, thiab nws cov kev ua tau zoo heev tau tso lub hauv paus tseem ceeb rau kev tshawb fawb ntawm kilowatt-chav kawm nruab nrab lub zog thiab ultrafast thin-film lasers ntawm 100 mJ.
