Muukadaulo wamakono wa laser, ma module opopa a diode akhala gwero loyenera la mpope la ma lasers olimba-boma ndi CHIKWANGWANI chifukwa chakuchita bwino kwawo, kudalirika, komanso kapangidwe kake. Komabe, chimodzi mwazinthu zovuta zomwe zimakhudza ntchito yawo yotulutsa ndi kukhazikika kwadongosolo ndikufanana kwa kugawa kwa phindu mkati mwa module ya pampu.
1. Kodi Gain Distribution Uniformity ndi chiyani?
M'ma modules opopera ma diode, mipiringidzo yambiri ya laser diode imakonzedwa mosiyanasiyana, ndipo kuwala kwawo kwapampu kumaperekedwa kumalo opindula (monga Yb-doped fiber kapena Nd: YAG crystal) kupyolera mu optical system. Ngati kugawa mphamvu kwa nyali ya mpope sikuli kofanana, kumabweretsa phindu la asymmetric pakati, zomwe zimapangitsa:
①Kuwonongeka kwa mtengo wamtengo wa laser
②Kuchepetsa mphamvu yosinthira mphamvu
③Kuchulukitsa kupsinjika kwamafuta ndikuchepetsa moyo wadongosolo
④Kuopsa kwakukulu kwa kuwonongeka kwa kuwala pakugwira ntchito
Chifukwa chake, kukwanilitsa kufanana kwapang'onopang'ono pakugawa kuwala kwapampu ndicholinga chofunikira kwambiri pakupanga ndi kupanga gawo la pampu.
2. Zomwe Zimayambitsa Kugawira Mapindu Opanda Uniform
①Kusiyana kwa Mphamvu ya Chip Emission
Ma tchipisi a laser diode amawonetsa kusiyanasiyana kwamphamvu. Popanda kusanja bwino kapena kulipidwa, kusiyana kumeneku kungapangitse kuti pampu ikhale yosagwirizana ndi dera lomwe mukufuna.
②Zolakwika mu Collimation ndi Focusing Systems
Zolakwika kapena zolakwika pazigawo zowoneka bwino (mwachitsanzo, ma lens a FAC/SAC, ma microlens array, ma fiber couplers) zitha kupangitsa kuti magawo a mtengowo apatukane ndi zomwe akufuna, ndikupanga malo ofikira kapena kufa.
③Thermal Gradient Zotsatira
Ma laser a semiconductor amakhudzidwa kwambiri ndi kutentha. Kapangidwe kocheperako ka heatsink kapena kuzizira kosagwirizana kungayambitse kutsetsereka kwa mafunde pakati pa tchipisi tosiyanasiyana, kusokoneza kulumikizana bwino komanso kusasinthika.
④Kusakwanira kwa Fiber Output Design
Mu multi-core fiber kapena zophatikizira zophatikizira zotulutsa, masanjidwe olakwika apakati amathanso kupangitsa kuti pampu isagawane kuwala kwapampu pakati pakupeza sing'anga.
3. Njira Zothandizira Kupeza Kufanana
①Kusintha kwa Chip ndi Kufananitsa Mphamvu
Yesani molondola ndi tchipisi ta laser diode kuti muwonetsetse kuti mphamvu yotulutsa imatuluka mkati mwa gawo lililonse, kuchepetsa kutenthedwa komweko ndikupeza malo otentha.
②Kapangidwe ka Optical Optimized
Gwiritsani ntchito ma optics osajambula kapena ma homogenizing ma lens (monga ma microlens array) kuti muwongolere kulumikizana kwa nsonga ndi kuyang'ana molondola, motero kusalaza mawonekedwe a mpope.
③Kuwongolera Kutentha Kwambiri
Gwiritsani ntchito zida zopangira matenthedwe apamwamba (mwachitsanzo, CuW, CVD diamondi) ndi njira zofananira zowongolera kutentha kuti muchepetse kusinthasintha kwa kutentha kwa chip-to-chip ndikusunga kutulutsa kokhazikika.
④Kuwala Kwambiri Homogenization
Phatikizani zowulutsira kapena zinthu zopanga ma lalanje panjira yowunikira pampu kuti mukwaniritse kufalikira kwapang'onopang'ono kwa kuwala mkati mwa njira yopezera phindu.
4. Phindu Lothandiza Pamapulogalamu Adziko Lonse
M'machitidwe apamwamba a laser-monga processing mwatsatanetsatane mafakitale, asilikali laser udindo, mankhwala, ndi kafukufuku sayansi-kukhazikika ndi mtengo wamtengo wa laser ndi wofunikira kwambiri. Kugawa kopanda yunifolomu kumakhudza mwachindunji kudalirika ndi kulondola kwadongosolo, makamaka muzochitika zotsatirazi:
①Ma laser amphamvu kwambiri: Amapewa machulukitsidwe am'deralo kapena zotsatira zopanda malire
②Fiber laser amplifiers: Imapondereza ASE (Amplified Spontaneous Emission)
③LIDAR ndi machitidwe opeza mitundu: Imawongolera kulondola kwa kuyeza komanso kubwereza
④Ma lasers azachipatala: Amawonetsetsa kuwongolera mphamvu moyenera panthawi yamankhwala
5. Mapeto
Kupeza kufanana kogawa sikungakhale kowonekera kwambiri pagawo la pampu, koma ndikofunikira kuti pakhale mphamvu zodalirika zamachitidwe a laser apamwamba. Pamene zofuna za mtundu wa laser ndi kukhazikika zikupitilira kukwera, opanga ma module a pampu ayenera kuchiza“kulamulira kofanana”monga core process-kuyeretsa mosalekeza kusankha kwa chip, kapangidwe kake, ndi njira zotenthetsera zoperekera magwero odalirika komanso osasinthika a laser kumayendedwe akumunsi.
Mukufuna kudziwa momwe timakwaniritsira kuti tipeze kufanana pamapampu athu? Lumikizanani nafe lero kuti mudziwe zambiri za mayankho athu ndi chithandizo chaukadaulo.
