Laser ndiye gawo lalikulu la zida zopangira laser, mulingo waukadaulo wa laser wakhala chinthu chofunikira kwambiri chomwe chikukhudza mulingo waukadaulo wa zida zopangira laser, laser ya ku China yakhala ikugwiritsa ntchito labotale, mulingo wa mafakitale ang'onoang'ono ndi apakatikati, idzalowa mu gawo lalikulu la mafakitale opangira, mulingo wotumizira mafakitale ndi mulingo wa msika zikukula mwachangu ndi chitukuko cha makampani. M'tsogolomu, akuyembekezeka kuti kukula kwa msika wamakampani kudzapitirira kukula motsatira mfundozi.
Deta yaikulu ya pepalali: chiwerengero cha mabizinesi mumakampani opanga laser a ultrafast, kutumiza kwa ultrafast femtosecond ultrafast laser, kukula kwa msika wa makampani opanga laser a ultrafast, ndi zina zotero. Laser ya Ultrafast imatanthauza laser yokhala ndi nthawi yochepa ya pulse ya laser. Poyerekeza ndi nanosecond laser, nthawi ya pulse ya laser ya ultrafast ndi yochepa kwambiri, mphamvu ya nthawi yomweyo ndi yayikulu kwambiri, mphamvu imayang'ana kudera laling'ono kwambiri ndipo silikhudzidwa ndi kuchuluka kwa pulse repetition ndi mphamvu yapakati, mtundu wa beam ndi wokhazikika.
Kuyambira mu 1961, pamene laser yoyamba ya ruby ku China idapangidwa ndi Changchun Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, ukadaulo wa laser wadutsa munjira yofulumira yopangira zinthu kwa zaka zoposa 50. Ponena za chitukuko cha mafakitale, kuyambira m'ma 1990, makampani akale a laser adayamba kupanga laser ya ultra-short pulse. M'zaka zaposachedwa, chifukwa cha kusintha kosalekeza kwa kukhazikika, laser yayamba kugwiritsidwa ntchito m'makampani akuluakulu.
Ponena za kufunikira kwa msika wa laser ya ultrafast, malinga ndi ziwerengero za 2021 China Laser Industry Development Report yomwe idatulutsidwa pamodzi ndi Wuhan Literature and Information Center of Chinese Academy of Sciences, Chinese Laser Journal, Chinese Optical Society ndi mabungwe ena, kutumiza kwa laser ya ultrafast femtosecond ultrafast ku China kudakwera chaka ndi chaka kuyambira 2015 mpaka 2020, ndi kukula kwa chiwopsezo choposa 50%. Mu 2020, China idatumiza lasers 2,100 za femtosecond ultra-fast, zomwe zidakwera ndi 52.2 peresenti pachaka.
Ponena za kukula kwa msika, malinga ndi ziwerengero za Wuhan Literature and Information Center of Chinese Academy of Sciences, kuchuluka kwa malonda a laser yothamanga kwambiri ku China kunakula mofulumira kuyambira 2015 mpaka 2020. Mu 2020, kuchuluka kwa malonda a laser yothamanga kwambiri ku China kunapitirira 2.7 biliyoni yuan, ndi kukula kwa chaka ndi chaka kwa 10.20%. Chiŵerengero chapakati cha kukula kwa msika wa laser yothamanga kwambiri pachaka kuyambira 2015 mpaka 2020 ndi pafupifupi 56.24%.
Laser ndiye gawo lalikulu la zida zopangira laser, ndipo mulingo waukadaulo wa laser umakhala chinthu chofunikira chomwe chimakhudza mulingo waukadaulo wa zida zopangira laser. Laser yopangira micro-machining ipitilizabe kukula mpaka kutalika kwa kutalika kwa nthawi, kutalika kwa pulse yopapatiza komanso mphamvu yayikulu, ndipo zochitika zogwiritsira ntchito micro-machining zidzakulitsidwa kwambiri. Ndondomeko ya Zaka Zisanu ya 14 ya Chitukuko cha Zachuma ndi Chikhalidwe cha Dziko ndi Ndondomeko ya Zolinga za Masomphenya a 2035 za People's Republic of China, zomwe zidatulutsidwa mu Marichi 2021, zidaperekedwa kuti zilimbikitse kukonza ndi kuphatikiza machitidwe atsopano otsogozedwa ndi zosowa zadziko, ndikufulumizitsa kumanga mphamvu zasayansi ndi ukadaulo zotsogozedwa ndi ma laboratories adziko. Ma laboratories angapo adziko adzakhazikitsidwa kuti aziyang'ana kwambiri magawo akuluakulu opanga zinthu monga chidziwitso cha quantum, photonics ndi ma micro and nano electronics, ndipo ma laboratories ofunikira adziko lonse adzakonzedwanso kuti apange dongosolo la labotale lokhala ndi kapangidwe koyenera komanso magwiridwe antchito abwino.
Motsogozedwa ndi maziko awiri a kafukufuku wa sayansi ndi kukulitsa kufunikira, mphamvu ya msika wa laser ya ultra-short pulse yomwe imayimiridwa ndi picosecond ndi femtosecond ipitiliza kukwera. Chifukwa chake, zikuyembekezeredwa kuti kukula kwa msika wamakampani opanga laser ya ultrafast ku China kudzasunga chiwongola dzanja cha pafupifupi 15%. Akuti kukula kwa msika wamakampani opanga laser ya ultrafast ku China kudzafika pafupifupi 6.2 biliyoni yuan mu 2026.
