Laser ili ndi mikhalidwe inayi, yowala kwambiri, mayendedwe abwino, monochromaticity yabwino, komanso kulumikizana kwakukulu.Zinthu izi zimagwirizana wina ndi mzake, zomwe zimapangitsa kuti laser ikhale yoyenera pazochitika zosiyanasiyana.
Kuwala kwakukulu kwa laser ndi chinthu chofunikira chosiyana ndi magwero a kuwala wamba, ndipo kuonjezera mphamvu ndi kuwala ndi mutu wamuyaya pa chitukuko cha lasers.Chomwe chili chowala kwambiri, chofotokozedwa m'chilankhulo chaukadaulo ndikuti chapafupi ndi 1 ndi index M2 yofotokoza mtundu wa mtengo.
M'zaka zaposachedwa, ndikusintha kwaukadaulo, ma laser a m'nyumba zapakhomo adutsa pang'onopang'ono mphamvu, kuchokera ku 12KW mpaka 20KW.Pakadali pano, laser fiber yapamwamba kwambiri yokhala ndi mphamvu ya 30KW yakhazikitsidwa pamsika, ndipo gawo lotsatira ndi 50KW.Aliyense amatchera khutu ndikupikisana ndi omwe mphamvu zake zotulutsa laser ndizokwera, koma amanyalanyaza yemwe ali ndi mtengo wabwinoko.
Lero tiyeni tiwone zomwe kuwala kwapamwamba, ndi ubwino ndi kufunikira kwa kuwala kwakukulu.
Makhalidwe a mtengo wa laser
Kuwala kwa laser komwe kumatulutsidwa ndi laser kumawoneka motere, koyamba kutembenukira kumunda wapafupi, kenako kufalikira kumunda wakutali.
mu,
Radiyo wa m'chiuno w0 ndi radius yomwe mtengo wa laser umasinthira ku gawo laling'ono kwambiri pamunda wapafupi;
The Rayleigh kutalika ZR ndi udindo pamene mtengo m'chiuno chawonjezeka ndi √2 nthawi;
Munda wakutali umatanthauzidwa ngati maulendo opitirira nthawi za 4 kutalika kwa Rayleigh, ndipo malo oyandikana nawo amatanthauzidwa ngati maulendo mkati mwa nthawi 4 kutalika kwa Rayleigh;
Mbali yakutali ya divergence angle θ imayimira kusiyanasiyana kwa mtengo wa laser kumunda wakutali.
Makhalidwe a Beam Quality
Mtengo wamtengo wapatali ndiye chizindikiro chachikulu chowonetsera mawonekedwe a mtengo wa laser, ndipo ndichizindikiro chofunikira cha laser, chomwe chimagwiritsidwa ntchito kuyeza kuchuluka kwa mtengo wa laser muzochitika zinazake.Njira zomwe zimagwiritsidwa ntchito powerengera mtengo wamtengo ndi: mtengo wamtengo wapatali (BPP) ndi M2chinthu.
BPP (Beam Parameter Product): mtengo wamtengo wapatali, womwe umatanthauzidwa ngati utali wa m'chiuno (w)0) kuchulukitsa ndi mbali yakutali (θ):
M2: Chiŵerengero cha mtengo wamtengo wapatali wa mtengo wamtengo wapatali wamtengo wapatali wa Gaussian, womwe ukhoza kusinthidwa kukhala BPP:
Kuchokera pamndandanda womwe uli pamwambapa, titha kupeza kuti: BPP ilibe chochita ndi kutalika kwa mawonekedwe, pomwe M2 factor ikugwirizana ndi laser wavelength.
Mtengo wa M² factor uli pafupi kwambiri ndi 1, zomwe zikutanthauza kuti chiwerengero cha deta yeniyeni ndi deta yabwino.Pamene deta yeniyeni ili pafupi ndi deta yabwino, khalidwe la mtengo limakhala bwino.
Kwa laser fiber yokhala ndi kutalika kwa 1070nm, magawo abwino ayenera kukhala:
Pamene CHIKWANGWANI laser BPP kapena M2parameterili pafupi ndi mtengo uwu, mtengo wamtengowo ndi wabwinoko ndipo ngodya yofananira ndiyocheperako.
Momwe mungadziwire mtundu wa mtengo
Nthawi zambiri, timagwiritsa ntchito chowunikira chamtengo kuyeza mtundu wa laser, lolani chowunikira chisunthike kunjira ya kuwala, ndikusonkhanitsa chidziwitso cha X, Y, ndi Z pamalo angapo kuti tidziwe kukula kwa chiuno, malo, ndi ngodya yosiyana. , ndikuwerengera kutalika kwa Rayleigh ndi BPP kapena M2.
Zomwe zimagwiritsidwa ntchito kwambiri ndi njira ya mpeni ndi njira yopatulira.Malingaliro a awiriwa ali ofanana, ndiye kuti, gwiritsani ntchito mpeni-m'mphepete kapena kung'ambika kuti muyang'ane mtengo, kuyeza ndi mapu kugawidwa kwa gawo, ndiyeno yendani mmwamba ndi pansi kuti muyese ndikujambula malo ounikirapo. mtunda wosiyana.Potsirizira pake, kugawidwa kwa magawo atatu a kuwala kumapezeka.

▲ Njira yogawa
Mayeso a mtengo wamtengo nthawi zambiri amakhala ovuta.Mwachidule, titha kuyerekeza kuyerekeza molingana ndi kuchuluka kwa fiber core diameter ndi manambala aperture (NA).
Nyali ya kuwala, ngakhale kukula kwa ngodyayo ndi yayikulu bwanji, imatha kupatsirana nthawi zonse ikalowa mu ulusi mkati mwa ngodya yovuta kwambiri.Phindu la sine la ngodya iyi α ndilobowo la nambala NA la ulusi, ndiko kuti, NA=sinα, lomwe limasonyeza kuwala kolandiridwa ndi ulusi.luso.Izo zikhoza kuganiziridwa pafupifupi izo.
Kodi nthawi zambiri timatanthawuza chiyani ndi ma laser owala kwambiri?
Kuwala (Br) Tanthauzo: Kachulukidwe wa mphamvu pagawo lililonse ndi ngodya yolimba ya unit.Monga tanena kale, gawo lalikulu la fiber laser
, mbali yakutali yolimba
.
Malinga ndi ndondomeko yomwe ili pamwambayi, sikovuta kuona kuti chotchedwa kuwala kwakukulu kumatanthauza kuti ili ndi mtengo wapamwamba kwambiri (ndiko kuti, BPP yaying'ono kapena M).2 ) pansi pa mphamvu yomweyo.
Monga mtsogoleri wapadziko lonse lapansi mu lasers zowala kwambiri,GW Laser Tech imayang'ana kwambiri kafukufuku ndi chitukuko cha 976nm high-brightness fiber lasers, zomwe zikutsogolera chitukuko cha lasers fiber.
Laser ya Guanghuindi single-njira 10mkuchepetsa CHIKWANGWANI linanena bungwe laser, M2<1.1, ndi 50kw 100μm CHIKWANGWANI laser ali ndi kachulukidwe mphamvu pafupi malire thupi.
Ochiritsira 100μm pachimake awiri-mode single-mode 4kW laser M2<1.3, Mipikisano mode 12kW laser BPP <4.

Kufunika ndi ubwino wa kuwala kwakukulu
M'zaka zaposachedwa, ma lasers amphamvu kwambiri pang'onopang'ono akukhala mphamvu yayikulu pamsika, ndipo ma laser a fiber nawonso akupita ku mphamvu zapamwamba.Ma lasers a 12KW akhala makonzedwe okhazikika a opanga ma laser ambiri.Chaka chatha, malonda a Guanghui Laser a 20KW lasers adakula kwambiri;pakadali pano, ma lasers a 40KW pang'onopang'ono akuyamba kutumiza.
Ma lasers ambiri amakono amphamvu kwambiri amapangidwa ndi ma module angapo, ndiye kuti, kuwala komwe kumapangidwa ndi ma module angapo a laser kumaphatikizidwa kukhala CHIKWANGWANI chimodzi chotulutsa.Poyerekeza ndi zotulutsa CHIKWANGWANI pachimake cha single laser module, angapo ma modules The ophatikizana linanena bungwe CHIKWANGWANI pachimake m'mimba mwake ndi yaikulu ndipo khalidwe mtengo ndi motere otsika.
Ngati mtengo wamtengowo umanyalanyazidwa, ziribe kanthu kuti mphamvuyo ndi yokwera bwanji, imatha kuzindikirika kudzera mu dongosolo lophatikizira ma module ambiri.Komabe, ndi kupita patsogolo kwaukadaulo ndi kukweza kwa mafakitale, makampani opanga zinthu adzapita pang'onopang'ono kupita ku mapeto apamwamba, omwe mosakayikira adzapereka zofunikira zapamwamba ndi zapamwamba za lasers, osati kungokwaniritsa kuwonjezeka kwa mphamvu, komanso kumvetsera kwambiri kusintha kwa kuwala. .Ma lasers amphamvu kwambiri omwe amangowonjezera mphamvu popanda kulabadira kuwala atha posachedwa ndi msika.
Kuyambira kukhazikitsidwa kwake, GW Laser Techwadzipereka ku kafukufuku ndi chitukuko cha ma laser owala kwambiri, ndipo adzawonjezera mphamvu ndikuwonjezera kuwala mofanana.Kupyolera mu kukhathamiritsa kwa single laser module teknoloji, fiber fusion splicing, ndi ndondomeko zophatikizira matabwa, kuwala kwa laser kwasinthidwanso.Pansi pa mphamvu zomwezo, pambuyo pa kuwombana ndi kuyang'ana ndi mawonekedwe omwewo, malo omwe ali pakatikati amakhala ang'onoang'ono ndipo kachulukidwe ka mphamvu ndipamwamba.Izi mwachindunji kuwonetseredwa mu ntchito laser processing: pansi pa mphamvu yomweyo, liwiro processing ndi mofulumira;pansi pa liwiro lomwelo pokonza, mphamvu yofunikira ndi yaying'ono.
Tengani chitsanzo cha GW Laser's YLPM 20KW laser kudula monga chitsanzo.Poyerekeza ndi ma lasers ena pa mphamvu yomweyo, kuthamanga kwachangu kumathamanga, ndipo mwayi uwu ndiwowonekera kwambiri podula zipangizo zowonetsera kwambiri.
Ma laser owala kwambiri ndi njira yofunikira pakukula kwamakampani a laser.Msika wamakono wa laser wamphamvu kwambiri wawonetsa homogeneity yodziwikiratu, ndipo opanga ma laser akuluakulu akupita patsogolo motsogozedwa ndi mphamvu zapamwamba.
GWLasersikuti amangoganizira za kuwonjezeka kwa mphamvu ya laser, komanso amasamalira kwambiri kusintha kwa kuwala kwa laser.M'tsogolomu, tidzapitiriza kufufuza njira yowala kwambiri, kuti laser ikhale ndi mtengo wabwino wamtengo wapatali ndi ntchito yokonza, ndipo imathandiza makasitomala kuwongolera bwino.
