Papita zaka zoposa 60 chiyambire pamene “nyezi ya kuwala kogwirizana” inayamba kupangidwa mu labotale ya ku California mu 1960. Monga momwe anatulukira laser, TH Maiman, anati, “Laser ndi njira yothetsera vuto pofufuza vuto.” Laser, ngati chida, Ikulowa pang'onopang'ono m'magawo ambiri monga kukonza mafakitale, kulumikizana ndi kuwala, ndi makompyuta.
Makampani a laser aku China, omwe amadziwika kuti "Mafumu a Involution", amadalira "mtengo-pa-volume" kuti atenge gawo la msika, koma amalipira mtengo wa phindu lotsika.
Msika wapakhomo wagwera mumpikisano wowopsa, ndipo makampani a laser atembenukira kunja ndikuyenda panyanja kufunafuna "kontinenti yatsopano" ya ma lasers aku China. Mu 2023, China Laser idayamba mwalamulo "chaka chake choyamba kupita kutsidya lanyanja." Pachiwonetsero cha Munich International Light Expo ku Germany kumapeto kwa June chaka chino, makampani oposa 220 aku China adawonekera pagulu, ndikupangitsa kuti dziko likhale ndi chiwerengero chachikulu cha owonetsa kupatulapo Germany.
Kodi bwato ladutsa Mapiri a Zikwi Khumi? Kodi China Laser ingadalire bwanji "voliyumu" kuti ikhale yolimba, ndipo iyenera kudalira chiyani kuti ipite patsogolo?
1. Kuyambira “zaka khumi zagolide” mpaka “msika wotulutsa magazi”
Monga woimira matekinoloje omwe akubwera, kafukufuku wamsika wa laser wapakhomo sanayambike mochedwa, kuyambira nthawi yomweyo ngati mayiko akunja. Laser yoyamba padziko lapansi inatuluka mu 1960. Pafupifupi nthawi yomweyo, mu August 1961, laser yoyamba ya China inabadwa ku Changchun Institute of Optics and Mechanics ya Chinese Academy of Sciences.
Pambuyo pake, makampani akuluakulu opanga zida za laser padziko lonse lapansi adakhazikitsidwa. M'zaka khumi zoyambirira za mbiri ya laser, Bystronic ndi Coherent adabadwa. Pofika m'ma 1970, II-VI ndi Prima adakhazikitsidwa motsatizana. TRUMPF, mtsogoleri wa zida zamakina, adayambanso ku 1977. Atabweretsanso laser CO₂ kuchokera ku ulendo wake ku United States ku 2016, bizinesi ya laser ya TRUMPF inayamba.
Pambuyo pakukula kwa mafakitale, makampani a laser aku China adayamba mochedwa. Laser ya Han inakhazikitsidwa mu 1993, Huagong Technology inakhazikitsidwa mu 1999, Chuangxin Laser inakhazikitsidwa mu 2004, JPT inakhazikitsidwa mu 2006, ndipo Raycus Laser inakhazikitsidwa mu 2007. Makampani ang'onoang'ono a laser awa alibe mwayi woyamba, koma khalani ndi mphamvu yoti mudzachite pambuyo pake.
M'zaka 10 zapitazi, ma lasers aku China adakumana ndi "zaka khumi zagolide" ndipo "kulowa m'malo mwapakhomo" kuli pachimake. Kuyambira 2012 mpaka 2022, kuchuluka kwapachaka kwamakampani opanga zida za laser kupitilira 10%, ndipo mtengo wake udzafika 86.2 biliyoni pofika 2022.
M'zaka zisanu zapitazi, msika wa fiber laser walimbikitsa kwambiri kulowetsedwa kwapakhomo pa liwiro lowoneka ndi maso. Gawo lamsika la ma lasers apanyumba lakwera kuchoka pa 40% kufika pafupifupi 70% m'zaka zisanu. Gawo lamsika la American IPG, lotsogola kwambiri la fiber laser, ku China latsika kwambiri kuchoka pa 53% mu 2017 kufika 28% mu 2022.

Tisatchule msika wamagetsi otsika, womwe wakwaniritsa m'malo mwapakhomo. Poyang'ana "mpikisano wa 10,000-watt" pamsika wamagetsi apamwamba, opanga pakhomo amapikisana wina ndi mzake, kusonyeza "China Speed" mokwanira. Zinatenga IPG zaka 13 kuchokera kutulutsidwa kwa laser yoyamba padziko lonse ya 10-watt-grade fiber fiber mu 1996 mpaka kutulutsidwa kwa laser 10,000-watt fiber, pomwe zidangotenga zaka 5 kuti Raycus Laser achoke pa 10 Watts kupita ku 10,000. watts.
Pampikisano wa 10,000-watt, opanga zopanga zapakhomo alowa nawo nkhondoyi motsatizana, ndipo kugulitsa kwawoko kukupita patsogolo kwambiri. Masiku ano, ma watts 10,000 salinso nthawi yatsopano, koma tikiti yamabizinesi kuti alowe mu bwalo la laser mosalekeza. Zaka zitatu zapitazo, Laser ya Chuangxin itawonetsa laser yake ya 25,000-watt fiber ku Shanghai Munich Light Expo, idadzetsa kuchuluka kwa magalimoto. Komabe, paziwonetsero zosiyanasiyana za laser chaka chino, "10,000 watt" yakhala muyezo wamabizinesi, ndipo ngakhale 30,000 watt, The 60,000-watt label ikuwonekanso wamba. Kumayambiriro kwa Seputembala chaka chino, Pentium ndi Chuangxin adakhazikitsa makina odulira laser oyambira padziko lonse lapansi a 85,000-watt, ndikuphwanya mbiri ya laser wattage kachiwiri.
Panopa mpikisano wa 10,000 watt watha. Makina odulira laser alowa m'malo mwa njira zachikhalidwe monga plasma ndi kudula kwamoto m'munda wa kudula mbale ndi wandiweyani. Kuchulukitsa mphamvu ya laser sikudzathandizanso kwambiri pakudula bwino, koma kumawonjezera ndalama komanso kugwiritsa ntchito mphamvu. .

Ngakhale kuti mpikisano wa 10,000-watt unali chigonjetso chotheratu, "nkhondo yamtengo wapatali" yowopsya inabweretsanso zowawa ku makampani a laser. Zinangotengera zaka 5 kuti gawo lapakhomo la ma fiber lasers lidutse, ndipo zidangotenga zaka 5 kuti mafakitale a laser fiber achoke pakupeza phindu lalikulu kupita ku phindu laling'ono. M'zaka zisanu zapitazi, njira zochepetsera mitengo yakhala njira yofunika kwambiri yotsogolera makampani apakhomo kuti awonjezere msika. Ma laser apakhomo "agulitsa mtengo wa voliyumu" ndikusefukira pamsika kuti apikisane ndi opanga kunja, ndipo "nkhondo yamitengo" yakula pang'onopang'ono.
Laser ya fiber 10,000-watt yomwe idagulitsidwa mpaka ma yuan 2 miliyoni mu 2017. Pofika chaka cha 2021, opanga m'nyumba adachepetsa mtengo wake mpaka 400,000 yuan. Chifukwa cha mwayi wake waukulu wamtengo wapatali, gawo la msika la Raycus Laser linamanga IPG kwa nthawi yoyamba mu gawo lachitatu la 2021, ndikupeza mbiri yakale yolowa m'malo mwanyumba.
Kulowa mu 2022, pamene chiwerengero cha makampani a laser apanyumba chikuwonjezeka, opanga laser alowa mu "involution" mpikisano wina ndi mzake. Bwalo lalikulu lankhondo pankhondo yamtengo wa laser lasintha kuchoka pagawo lamphamvu la 1-3 kW kupita ku gawo lamphamvu kwambiri la 6-50 kW, ndipo makampani akupikisana kuti apange ma laser amphamvu kwambiri. Makuponi amtengo, makuponi a ntchito, ndi opanga ena apakhomo adayambitsanso dongosolo la "zero down payment", kuyika zida zaulere kwa opanga otsika kuti ayesedwe, ndipo mpikisano udakula.
Pamapeto pa "mpukutu", makampani a laser thukuta sanadikire kuti akolole bwino. Mu 2022, mtengo wa fiber lasers pamsika waku China udzatsika ndi 40-80% pachaka. Mitengo yapakhomo ya zinthu zina yatsitsidwa kufika pa gawo limodzi mwa magawo khumi a mitengo yochokera kunja. Makampani makamaka amadalira kuchulukitsidwa kwa katundu kuti akhalebe ndi phindu. Domestic fiber laser chimphona Raycus awona kuwonjezeka kwakukulu pachaka kwa kutumiza, koma ndalama zake zogwirira ntchito zidatsika ndi 6.48% pachaka, ndipo phindu lake lonse limatsika ndi 90% pachaka. Ambiri opanga zapakhomo omwe bizinesi yawo yayikulu ndi lasers awona phindu lakuthwa mu 2022 likutsika.

Ngakhale makampani otsogola akunja adakumana ndi zovuta mu "nkhondo yamitengo" pamsika waku China, kudalira maziko awo akuya, ntchito yawo siinatsike koma idakula.
Chifukwa cha kulamulira kwa TRUMPF Gulu pa EUV lithography makina opangira kuwala kwa kampani yaukadaulo yaku Dutch ASML, kuchuluka kwake mchaka chachuma cha 2022 kudakwera kuchokera ku 3.9 biliyoni mu nthawi yomweyi chaka chatha kufika mabiliyoni 5.6, kuwonjezeka kwakukulu kwa chaka ndi chaka. 42%; Kugulitsa kwa Gaoyi muchuma cha 2022 pambuyo pakupeza Guanglian Revenue kudakwera ndi 7% pachaka, ndipo kuchuluka kwa madongosolo kudafika US $ 4.32 biliyoni, kuwonjezeka kwa chaka ndi 29%. Kugwira ntchito kudaposa zomwe zinkayembekeza kotala lachinayi motsatizana.
Pambuyo kutayika pamsika waku China, msika waukulu kwambiri wa laser processing, makampani akunja atha kukwaniritsa magwiridwe antchito apamwamba. Kodi tingaphunzirepo chiyani panjira yachitukuko cha laser chamakampani otsogola padziko lonse lapansi?
2. "Kuphatikizika koyima" motsutsana ndi "kuphatikiza kwa diagonal"
Ndipotu, msika wapakhomo usanafike pa 10,000 watts ndikuyambitsa "nkhondo yamtengo wapatali", makampani otsogola kunja kwa nyanja amaliza kusinthika patsogolo pa nthawi. Komabe, zomwe "adagubuduza" si mtengo, koma kapangidwe kazinthu, ndipo ayamba kuphatikizika kwamakampani kudzera pakuphatikizana ndi kugula. njira yowonjezera.
M'munda wa laser processing, makampani otsogola padziko lonse lapansi atenga njira ziwiri zosiyana: pamsewu wophatikizira wokhazikika kuzungulira unyolo wamakampani amodzi, IPG ndi sitepe imodzi patsogolo; pamene makampani oimiridwa ndi TRUMPF ndi Coherent asankha "Kuphatikizana kwa Oblique" kumatanthauza kuphatikizika koyima ndi kukulitsa gawo lopingasa "ndi manja onse awiri." Makampani atatuwa ayamba motsatizana nthawi zawo, zomwe ndi nthawi ya optical fiber yomwe imayimiridwa ndi IPG, nthawi ya disc yomwe imayimiridwa ndi TRUMPF, ndi nthawi ya mpweya (kuphatikizapo excimer) yoimiridwa ndi Coherent.
IPG imalamulira msika ndi fiber lasers. Kuchokera pamndandanda wake mu 2006, kupatula mavuto azachuma mu 2008, ndalama zogwirira ntchito ndi zopindulitsa zakhalabe zapamwamba. Kuyambira 2008, IPG yapeza opanga angapo okhala ndi ukadaulo wa zida monga zopatula zowonera, ma lens ophatikizira, ma fiber gratings, ndi ma module optical, kuphatikiza Photonics Innovations, JPSA, Mobius Photonics, ndi Menara Networks, kuti azitha kuphatikiza molunjika kumtunda kwa ndi fiber laser industry unyolo. .
Pofika mchaka cha 2010, kuphatikizika kwa IPG m'mwamba kunamalizidwa. Kampaniyo idakwanitsa pafupifupi 100% yodzipangira yokha ya zigawo zazikuluzikulu, patsogolo kwambiri kuposa omwe akupikisana nawo. Kuphatikiza apo, idatsogola paukadaulo ndikuyambitsa njira yaukadaulo yoyamba padziko lonse lapansi yaukadaulo ya fiber amplifier. IPG inali m'munda wa fiber lasers. Khalani molimba pampando wachifumu wadziko lonse lapansi.

Pakalipano, makampani a laser apakhomo, omwe atsekeredwa mu "nkhondo yamtengo wapatali", alowa mu gawo la "vertical integration". Phatikizani molunjika unyolo wamafakitale kumtunda ndikuzindikira kudzipanga kwazinthu zazikuluzikulu, potero kumakweza mawu azinthu pamsika.
Mu 2022, pamene "nkhondo yamtengo wapatali" ikukulirakulira, njira yolumikizira zida zazikuluzikulu idzakulitsidwa kwathunthu. Opanga ma laser angapo apanga zopambana m'munda wamitundu yayikulu yokhala ndi ukadaulo wa laser wa ytterbium-doped laser; mlingo wodzipangira wa zigawo zongokhala wakula kwambiri; Njira zina zapakhomo monga zodzipatula, ma collimators, zophatikizira, ma couplers, ndi ma fiber gratings akukhala otchuka kwambiri. Wokhwima. Makampani otsogola monga Raycus ndi Chuangxin atengera njira yophatikizira yokhazikika, yochita nawo kwambiri ma lasers a fiber, ndipo pang'onopang'ono apeza kuwongolera kodziyimira pawokha kwa zigawo powonjezera kafukufuku waukadaulo ndi chitukuko ndi kuphatikiza ndi kupeza.
Pamene "nkhondo" yomwe yakhalapo kwa zaka zambiri yatenthedwa, njira yophatikizira mabizinesi otsogola yakula, ndipo nthawi yomweyo, mabizinesi ang'onoang'ono ndi apakatikati azindikira mpikisano wosiyana muzosankha zomwe mwamakonda. Pofika chaka cha 2023, nkhondo yamtengo wapatali pamsika wa laser yafooka, ndipo phindu lamakampani a laser lakula kwambiri. Raycus Laser adapeza phindu lalikulu la yuan 112 miliyoni mu theka loyamba la 2023, kuchuluka kwa 412.25%, ndipo pamapeto pake adatuluka mumthunzi wa "nkhondo yamitengo".
Woimira njira ina yachitukuko ya "oblique integration" ndi TRUMPF Group. Gulu la TRUMPF lidayamba ngati kampani yopanga zida zamakina. Bizinesi ya laser poyamba inali makamaka ma laser a carbon dioxide. Pambuyo pake, idapeza HüTTINGER (1990), HAAS Laser Co., Ltd. (1991), Saxony Machine Tools ndi Special Machine Tools Co., Ltd. (1992), ndikukulitsa bizinesi yake yolimba ya laser. Mu bizinesi laser ndi madzi kudula makina, woyamba experimental chimbale laser anapezerapo mu 1999 ndipo kuyambira pamenepo mwamphamvu wotanganidwa udindo waukulu mu chimbale msika. Mu 2008, TRUMPF inapeza SPI, yomwe inatha kupikisana ndi IPG, kwa US $ 48.9 miliyoni, kubweretsa lasers fibers m'gawo lake lamalonda. Yapanganso kusuntha pafupipafupi m'munda wa lasers ultrafast. Lapeza motsatizanatsatizana ndi opanga ma laser a ultrashort pulse Amphos (2018) ndi Active Fiber Systems GmbH (2022), ndipo akupitilizabe kudzaza kusiyana kwa masanjidwe aukadaulo wa laser wothamanga kwambiri monga ma discs, slabs ndi makulidwe a fiber. "puzzle". Kuphatikiza pa masanjidwe opingasa a zinthu zosiyanasiyana za laser monga ma disc lasers, ma lasers a carbon dioxide, ndi ma fiber lasers, Gulu la TRUMPF limachitanso bwino pakuphatikizana koyima kwa unyolo wa mafakitale. Imaperekanso zida zonse zamakina kumakampani akumunsi ndipo ilinso ndi mwayi wopikisana pazida zamakina.

Njirayi imathandizira kuti mzere wonsewo udzipangire zokha kuchokera pazigawo zapakati mpaka kumaliza zida, kuyika mopingasa zinthu zamtundu wa laser, ndikupitilizabe kukulitsa malire azinthu. Han's Laser ndi Huagong Technology, omwe akutsogolera makampani apakhomo m'munda wa laser, akutsatira njira yomweyo, kuyika woyamba ndi wachiwiri pakati pa opanga zoweta pakugwiritsa ntchito ndalama chaka chonse.
Kusawoneka bwino kwa malire akumtunda ndi kunsi kwa mtsinje ndi mawonekedwe amakampani a laser. Chifukwa cha unitization ndi modularization ya ukadaulo, polowera kulowa sipamwamba. Ndi maziko awo ndi chilimbikitso chachikulu, palibe opanga ambiri apakhomo omwe amatha "kutsegula madera atsopano" m'njira zosiyanasiyana. Siziwoneka kawirikawiri. M'zaka zaposachedwa, opanga ena apakhomo alimbitsa pang'onopang'ono mphamvu zawo zophatikizira ndikusokoneza pang'onopang'ono malire a unyolo wa mafakitale. Maubwenzi oyambilira a kumtunda ndi kumunsi kwa mtsinjewo asintha pang'onopang'ono kukhala opikisana nawo, ndi mpikisano woopsa pa ulalo uliwonse.
Mpikisano wothamanga kwambiri wakula mwachangu makampani a laser aku China, ndikupanga "nyalugwe" yemwe saopa opikisana nawo akunja ndikupititsa patsogolo njira yotsatsira anthu. Komabe, zachititsanso kuti pakhale "moyo-ndi-imfa" wa "nkhondo zamtengo wapatali" komanso mpikisano wofanana. mkhalidwe. Makampani a laser aku China apeza njira yolimba podalira "mipukutu". Kodi m’tsogolomu adzachita chiyani?
3. Malamulo awiri: Kuyika matekinoloje atsopano ndikufufuza misika yakunja
Kudalira luso lamakono, tikhoza kuthetsa vuto la kutaya ndalama kuti tisinthe msika ndi mitengo yotsika; kudalira kunja kwa laser, tikhoza kuthetsa vuto la mpikisano woopsa pamsika wapakhomo.
Makampani a laser aku China adavutika kuti apeze atsogoleri akunja m'mbuyomu. Pankhani yoyang'ana kwambiri zolowa m'malo m'nyumba, misika yayikulu iliyonse yomwe ikukula imatsogozedwa ndi makampani akunja, zogulitsa zakomweko zikutsatira mwachangu mkati mwa zaka 1-2 ndikulowa m'malo mwazogulitsa zam'nyumba ndikugwiritsa ntchito zitakhwima. Pakalipano, padakali chodabwitsa cha makampani akunja omwe akutsogolera potumiza mapulogalamu m'mafakitale omwe akutukuka kumene, pamene zinthu zapakhomo zikupitiriza kulimbikitsa m'malo.
"Kulowa m'malo" sikuyenera kuima pakufuna "kusintha". Panthawi yomwe makampani a laser aku China akusintha, kusiyana pakati pa matekinoloje ofunikira a laser opanga m'nyumba ndi mayiko akunja akuchepa pang'onopang'ono. Ndikofunikira kuyika matekinoloje atsopano mwachangu ndikusaka kupitilira m'makona, kuti muchotse "kugwiritsa ntchito nthawi yabwino pamitengo yotengera voliyumu.
Ponseponse, kukhazikitsidwa kwa matekinoloje atsopano kumafuna kuzindikira kogulitsa kotsatira. Kusintha kwa laser kwadutsa nthawi yodula yomwe imayang'aniridwa ndi kudula zitsulo komanso nthawi yowotcherera yomwe imakhudzidwa ndi kuwonjezereka kwamphamvu kwatsopano. Kuzungulira kwamakampani kotsatira kumatha kusintha magawo opangira ma poto ngati ma pan-semiconductors, ndipo ma lasers ofananira ndi zida za laser zidzatulutsa kufunikira kwakukulu. "Match point" yamakampaniwo isinthanso kuchoka pa "10,000-watt mpikisano" wamagetsi opitilira mphamvu kwambiri kupita ku "mpikisano wothamanga kwambiri" wa ma ultra-short pulse lasers.
Kuyang'ana makamaka pazigawo zogawikana, titha kuyang'ana kwambiri zakuyenda bwino m'malo atsopano ogwiritsira ntchito kuyambira "0 mpaka 1" panthawi yaukadaulo watsopano. Mwachitsanzo, kulowetsedwa kwa maselo a perovskite kumayembekezereka kufika 31% pambuyo pa 2025. Komabe, zida zoyamba za laser sizingathe kukwaniritsa zofunikira zowonongeka kwa maselo a perovskite. Makampani a laser amayenera kuyika zida zatsopano za laser pasadakhale kuti akwaniritse kudziyimira pawokha kwaukadaulo wapakatikati. , kukonza phindu lalikulu la zida ndikutengera msika wamtsogolo. Kuonjezera apo, zochitika zolonjeza zogwiritsira ntchito monga kusungirako mphamvu, chithandizo chamankhwala, mawonetsero ndi mafakitale a semiconductor (laser lift-off, laser annealing, mass transfer), "AI + laser kupanga", etc. akuyeneranso kuyang'ana.
Ndi chitukuko chosalekeza chaukadaulo wapakhomo wa laser ndi zinthu, laser ikuyembekezeka kukhala khadi yabizinesi yamabizinesi aku China kupita kutsidya lina. 2023 ndi "chaka choyamba" cha lasers kupita kutsidya kwa nyanja. Poyang'anizana ndi misika ikuluikulu kunja kuti mwamsanga ayenera kuthyola, zida laser adzatsatira kutsika otsiriza opanga ntchito kupita kutsidya kwa nyanja, makamaka China "kutali kutsogolera" lifiyamu batire ndi mafakitale mphamvu galimoto latsopano, amene adzapereka mwayi kwa katundu wa zida laser. Nyanja imabweretsa mwayi wa mbiri yakale.
Pakadali pano, kupita kutsidya kwa nyanja kwakhala mgwirizano wamakampani, ndipo makampani akuluakulu ayamba kuchitapo kanthu kuti akulitse kukula kwakunja. M'chaka chatha, Han's Laser adalengeza kuti akufuna kuyika ndalama zokwana $60 miliyoni kuti akhazikitse kampani yocheperako "Green Energy Viwanda Development Co., Ltd." ku United States kuti afufuze msika waku US; Lianying yakhazikitsa kampani yocheperako ku Germany kuti ifufuze msika waku Europe ndipo pakali pano ikugwirizana ndi mafakitale angapo aku Europe a mabatire Tidzachita kusinthana kwaukadaulo ndi OEM; Haimixing idzayang'ananso pakufufuza misika yakunja kudzera m'mapulojekiti okulitsa akunja kwa mafakitale akunja ndi mabatire akunja ndi opanga magalimoto.
Ubwino wamtengo ndi "khadi lipenga" lamakampani a laser aku China kupita kutsidya lina. Zida zapakhomo za laser zili ndi ubwino wamtengo wapatali. Pambuyo pa kukhazikitsidwa kwa ma lasers ndi zigawo zikuluzikulu, mtengo wa zida za laser watsika kwambiri, ndipo mpikisano woopsa watsitsanso mitengo. Asia-Pacific ndi Europe akhala malo akuluakulu otumizira kunja kwa laser. Pambuyo popita kutsidya kwa nyanja, opanga zapakhomo azitha kumaliza malonda pamitengo yokwera kuposa mawu am'deralo, ndikuwonjezera phindu.
Komabe, gawo laposachedwa la malonda a laser omwe amachokera kumakampani a laser aku China akadali otsika, ndipo kupita kutsidya lanyanja kukakumana ndi zovuta monga kusakwanira kwamtundu wamtundu komanso kufooka kwautumiki wakumalo. Ikadali njira yayitali komanso yovuta kuti "kupita patsogolo".
Mbiri yachitukuko cha laser ku China ndi mbiri yankhondo yankhanza yotengera lamulo la nkhalango.
M’zaka khumi zapitazi, makampani a laser akumana ndi ubatizo wa “mpikisano wa 10,000-watt” ndi “nkhondo zamitengo” ndipo apanga “vanguard” yomwe ingapikisane ndi ma brand akunja kumsika wakunja. Zaka khumi zikubwerazi idzakhala nthawi yovuta kwambiri kuti ma lasers apakhomo asinthe kuchoka ku "msika wotuluka magazi" kupita ku luso lazopangapanga, komanso kuchoka m'malo mwa nyumba kupita kumsika wapadziko lonse. Pokhapokha poyenda bwino mumsewu uwu pomwe makampani opanga laser aku China angazindikire kusintha kwake kuchokera "kutsata ndi kuthamanga motsatira" kupita "Kutsogolera" kudumpha.
