BWT yapereka malingaliro a chiphunzitso cha dense spatial arrangement (DSBC) ndikutsimikizira kulondola kwa DSBC kudzera pakuyesa gwero la pampu ya kilowatt-level.Pakali pano, mphamvu ya chubu imodzi yawonjezeka kufika 15W-30W@BPP≈5-12mm*mrad ndipo mphamvu ya electro-optical ndi> 60%, yomwe imapangitsa kuti pampu yamphamvu kwambiri yophatikizidwa ndi fiber ituluke kuwala linanena bungwe pamene kuchepetsa voliyumu, N'zotheka kuchepetsa kulemera ndi kusintha electro-optical kutembenuka dzuwa.

Pogwiritsa ntchito chip chapano, BWT idazindikira gwero la mpope lomwe lili ndi mainchesi apakati a 135μm NA0.22 fiber-coupled linanena bungwe 420W wavelength-lotsekedwa pa 976nm, khalidwe ≈ 500g;ndi pakati pachimake cha 220μm NA0.22 CHIKWANGWANI ophatikizana linanena bungwe 1000W umodzi wavelength 976nm (kapena 915nm), khalidwe ≈ 400g mpope gwero.

M'tsogolomu, ndi kusintha kwa kuwala kwa semiconductor chip kuwala ndi electro-optical dzuwa, magwero opepuka komanso apamwamba amphamvu amagetsi adzakhala ndi gawo losasinthika popanga magwero ang'onoang'ono amphamvu kwambiri a fiber laser, ndipo adzalimbikitsa chitukukochi. za ntchito zamakampani.

Mawu Oyamba
Ma fiber lasers akula mwachangu chifukwa cha mtengo wawo wabwino kwambiri komanso kuthekera kosinthika kwamagetsi (zophatikiza ulusi).M'zaka zaposachedwa, single-mode single-fiber fiber lasers ndi yochepa ndi TMI (transverse mode kusakhazikika) ndi zotsatira za SRS, ndipo mphamvu ya semiconductor mwachindunji kupopa CHIKWANGWANI laser oscillators ndi malire 5kW.
[1].Laser amplifier imayimitsidwanso pa 10kW
[2].Ngakhale mphamvu yotulutsa imatha kuonjezedwa powonjezera m'mimba mwake moyenerera, mtengo wamtengowo umatsikanso -1.Komabe, kufunikira kowongolera kuwala kwa magwero a pampu ya semiconductor kukadali kofunikira.
Zofunikira za mtengo wamtengo pazantchito zamafakitale sizikhala zamtundu umodzi.Pofuna kuonjezera mphamvu ya single-fiber, njira zochepa zochepetsera zimaloledwa.Mpaka pano, magwero owunikira amtundu wa single-fiber ndi matabwa ophatikizika ndi ma 976nm kupopera oposa 5kW Ndi kugwiritsa ntchito batch (makamaka kudula ndi kuwotcherera kwa zida zachitsulo), kupanga magwero amphamvu amphamvu apompo. ilinso batch-scaled.
Zing'onozing'ono, zopepuka komanso zokhazikika
Ubale pakati pa semiconductor chip BPP ndi kuwala kwa gwero la mpope
Zaka zitatu zapitazo, kuwala kwa tchipisi 9xxnm kunali kwakukulu pamlingo wa 3W/mm*mrad@12W-100μm m'lifupi mwake & 2W/mm*mrad@18W-200μm m'lifupi mwake.Kutengera tchipisi zotere, BWT imakwaniritsa 600W ndi 1000W 200μm NA0.22 fiber-coupled linanena bungwe-1.
Pakadali pano, kuwala kwa tchipisi 9xxnm kwafikira 3.75W/mm*mrad@15W-100μm m'lifupi mwake & 3W/mm*mrad@30W-230μm m'lifupi mwake, ndipo mphamvu ya electro-optical imasungidwa pafupifupi 60%.
Malinga ndi chiphunzitso cha makonzedwe apakati a malo [6], amawerengedwa molingana ndi kuchuluka kwa fiber 78% (kutulutsa kwa laser kuchokera ku chip kupita ku fiber coupling linanena bungwe: single-wavelength spatial mtengo kuphatikiza ndi polarization mtengo kuphatikiza popanda VBG), ndipo zimaganiziridwa kuti chip chimagwira ntchito mwamphamvu kwambiri ( Chip BPP ndi yosiyana ndi mafunde osiyanasiyana), tapanga mapu a data motere:

* Chip Kuwala VS Different Core Diameter Fiber Coupling Output Power

Zitha kupezeka kuchokera pa chithunzi pamwambapa kuti ulusi wina (m'mimba mwake wapakati ndi NA utakhazikika) umakhala ndi mphamvu yapadera yolumikizira mphamvu, chifukwa cha tchipisi towala mosiyanasiyana, kuchuluka kwa tchipisi kumakhala kosiyana, komanso kuchuluka kwake ndi kulemera kwa gwero la mpope. nawonso ndi osiyana.Pazofunikira pakupopa kwa fiber laser, ngati gwero la mpope lopangidwa ndi tchipisi pamwambapa ndi kuwala kosiyana limasankhidwa, kulemera ndi voliyumu ya fiber laser yamphamvu yomweyi ndizosiyana kotheratu, komanso kasinthidwe ka njira yoziziritsira madzi ndiyosiyananso. zosiyana kwambiri.
Kuchita bwino kwambiri, kakulidwe kakang'ono komanso kulemera kopepuka ndizomwe sizingalephereke pakupanga magwero amtsogolo a kuwala kwa laser (kaya ma diode lasers, solid-state lasers kapena fiber lasers), komanso kuwala, mphamvu ndi mphamvu za semiconductor tchipisi zimatenga gawo lalikulu pamenepo. .
Wopepuka, wowala kwambiri, gwero lamphamvu lamphamvu kwambiri
Kuti tigwirizane ndi chophatikizira cha fiber, tinasankha zomwe zimafanana ndi fiber: 135μm NA0.22 ndi 220μm NA0.22.Mapangidwe owoneka bwino a magwero a mapampu awiriwa amatengera kukhazikika kwa malo ndi kuphatikizika kwa mtengo wa polarization.
Pakati pawo, 420WLD imatenga 3.75W/mm* mrad@15W chip ndi 135μm NA0.22 fiber, ndipo ili ndi VBG wavelength locking, yomwe imakwaniritsa zofunikira za 30-100% yotseka mafunde amphamvu, ndipo mphamvu ya electro-optical ndi 41% .Thupi la LD limapangidwa ndi aluminiyumu aloyi zinthu ndi masangweji kapangidwe [5].Tchipisi zam'mwamba ndi zam'munsi zimagawana njira yozizirira madzi, zomwe zimathandizira kugwiritsa ntchito malo.Kapangidwe ka malo owala, sipekitiramu ndi kutulutsa mphamvu (mphamvu mu ulusi) zikuwonetsedwa pachithunzichi:

*420W@135μm NA0.22 LD

Tinasankha 6 LDs kuti tiyese kutentha kwakukulu ndi kutsika kwa kutentha ndi kugwedezeka.Mayeso a data ndi awa:
