Thaum Lub Xya Hli 29, 2021, Leng Yuxin, tus thawj coj ntawm Shanghai Institute of Optics thiab Fine Mechanics ntawm Suav Academy ntawm Kev Tshawb Fawb, tau tshaj tawm rau Jiji Xov Xwm tias xyoo no, Shanghai lub ultra-muaj zog thiab ultra-luv laser sim tshuab (tseem hu ua "Xihe Laser Device") tau pib qhib. Thiab rau lub teeb ncov ntau lub koom haum tshawb fawb tshawb fawb thiab cov pab pawg tshawb fawb cuam tshuam ntawm Central South University kom ua tiav physics thwmsim; Cov kev sim xws li proton acceleration, electron acceleration, high-brightness plasma high-order harmonics thiab attosecond pulse generation tab tom ua.
Thaum Lub Kaum Ob Hlis 28 xyoo tas los, Xihe laser installation project tau koom tes txhawb nqa los ntawm National Development thiab Reform Commission thiab Shanghai. Nws tau suav nrog hauv Shanghai thawj pawg ntawm cov haujlwm tseem ceeb los tsim kom muaj lub ntiaj teb muaj kev cuam tshuam txog kev tshawb fawb thiab thev naus laus zis thiab tsim kom muaj lub ntiaj teb-chav kawm kev lag luam loj hauv kev lag luam. Nws tseem yog Zhangjiang Comprehensive Ib qho ntawm cov txheej txheem tseem ceeb ntawm National Science Center for Sexuality.
Xihe laser cuab yeej project tau tsim nyob rau lub Ib Hlis 4, 2016, pib thaum lub Kaum Ib Hlis 20, 2016, thiab dhau qhov kev lees paub rau lub Kaum Ob Hlis 28, 2020. Raws li ib qho tseem ceeb technology infrastructure project, qhov project tau tsim thaum lub sij hawm "13th Tsib-xyoo Plan" lub sij hawm. Tag nrho cov txheej txheem ntawm kev tsim kho, kev tsim kho thiab kev lees txais.
Thaum lub sij hawm tsim kho ntawm qhov project, thaum Lub Kaum Hli 24, 2017, cov cuab yeej ua tiav 10.3 petawatt laser amplification tso zis, uas yog thawj lub teb chaws ua tiav broadband laser amplification tso zis nrog lub zog ntawm ntau tshaj 300 joules, thiab mem tes dav yog 21 femtoseconds tom qab. mem tes compression.
Thaum Lub Kaum Ob Hlis 7, 2019, cov cuab yeej tau txais lub laser nrog lub nruab nrab wavelength ntawm 800 nanometers, lub zog tso zis ntawm 404 joules, rov ua dua tus nqi ntawm 3 feeb ib txhaj tshuaj (40 npaug siab dua qhov kev pom zoo Performance index), compressed mem tes dav ntawm 24.6. fs, thiab nruab nrab lub zog siab tshaj plaws ntawm 11.7 neeg ntaus. Qhov tshwm sim ntawm watts (lub siab tshaj plaws lub zog ntawm 12.9 petawatts) tsoo lub ntiaj teb cov ntaub ntawv dua.
Tib lub sijhawm, tso siab rau qhov project no, Shanghai Institute of Optics thiab Mechanics tau ua tiav cov khoom siv tseem ceeb xws li lub ntiaj teb txoj kab loj tshaj plaws Ti: Sapphire siv lead ua.
Leng Yuxin tau hais tias "Xihe laser device" muab cov kws tshawb fawb nrog lub cev muaj zog thiab muaj zog heev thiab xav tias yuav tau txais qee qhov txiaj ntsig tshiab hauv physics, cov ntaub ntawv tshawb fawb, kev tshawb fawb txog lub neej, kev tiv thaiv hauv tebchaws thiab kev ruaj ntseg, thiab lwm yam kev lag luam.
Nws tau tshaj tawm tias Shanghai ultra-muaj zog thiab ultra-luv laser kev sim ntaus ntawv feem ntau suav nrog: 10-PW (1 petawatt=1 petawatt) ultra-muaj zog thiab ultra-luv laser system, thiab {{ 7}}PW laser tso zis beam nrog siab repetition tus nqi. Kab; peb cov neeg siv kev sim terminals suav nrog cov xwm txheej huab cua tshawb fawb platform, ultrafast subatomic physics tshawb fawb platform, ultrafast chemistry thiab macromolecular dynamics tshawb fawb platform; kev tshawb fawb tshawb fawb pab chaw thiab cov ntaub ntawv chaw; ib qho cuab yeej sim tsev.
Raws li Leng Yuxin, Shanghai lub koom haum ntawm Optics thiab Mechanics ntawm Suav Academy ntawm Sciences tau tam sim no optimized lub laser ua hauj lwm raws li txoj cai, ntsuas thiab paub tseeb qhov tseem ceeb tsis thiab kev ua tau zoo ntawm lub laser system; thiab tsim ib hom kev ua haujlwm ua ntej, tsim ib pab neeg ua haujlwm thiab physics, thiab qhia meej txog kev faib cov dej num thiab cov neeg siv cov txheej txheem thov; tau tsim "Kev Tswj Xyuas Cov Neeg Siv Khoom", "Cov Neeg Siv Khoom Ua Haujlwm Cov Cai", "Open Guidelines" thiab lwm yam kev cai thiab cov cai los txiav txim rau cov npe ntawm pawg neeg siv.
Nyob rau hauv lub neej yav tom ntej, lub Xihe laser ntaus ntawv yuav qhib rau domestic thiab txawv teb chaws universities, scientific kev tshawb fawb cov koom haum thiab cov lag luam los muab cov ntaub ntawv zoo tshaj plaws science thiab life science txoj kev tshawb fawb. Txoj haujlwm no muab cov cuab yeej technology thiab cov txuj ci tseem ceeb rau kev tsim kho ntawm 100-PW ultra-strong thiab ultra-luv laser system, thiab yuav dhau los ua ib feem tseem ceeb ntawm Zhangjiang Comprehensive National Science Center photonic loj scientific device pawg.
