Pamene ntchito za laser zamphamvu kwambiri zikupitilira kukula, mipiringidzo ya laser diode yakhala yofunika kwambiri m'malo monga kupopera kwa laser, kukonza mafakitale, zida zamankhwala, ndi kafukufuku wasayansi. Ndi kachulukidwe kake kamphamvu ka mphamvu, modular scalability, komanso magwiridwe antchito apamwamba a electro-optical, zida izi ndizoyambira pamakina ambiri amakono a laser. Komabe pakati pa zizindikilo zambiri za kagwiridwe ka laser diode bar, gawo limodzi nthawi zambiri limanyalanyazidwa koma lofunikira kwambiri: mbali ya divergence. Nkhaniyi ikufotokoza za mawonekedwe, magwero a thupi, ndi zotsatira za kusiyana kwa mipiringidzo ya laser diode - ndi momwe mapangidwe a kuwala angayendetsere bwino.
1. Kodi Divergence Ale ndi Chiyani?
Divergence angle imafotokoza momwe mtengo wa laser umafalikira pamene ukufalikira mu malo aulere. Imawonetsa momwe mtengowo umakulirakulira kuchokera pagawo lotulutsa. M'mipiringidzo ya laser diode, mbali yosiyana imawonetsa asymmetry yolimba munjira ziwiri zazikulu:
Fast Axis: Perpendicular to the bar surface. Dera lotulutsa mpweya ndi lopapatiza kwambiri (nthawi zambiri 1–2 µm), zomwe zimatsogolera kumakona akulu akulu, nthawi zambiri 30°–45° kapena kupitilira apo.
Slow Axis: Kufanana ndi kutalika kwa bala. Dera lotulutsa mpweya ndilokulirapo (mazana a ma microns), zomwe zimapangitsa kuti pakhale ma angles ang'onoang'ono, nthawi zambiri kuzungulira 5 ° -15 °.
Kusiyana kwa asymmetric uku ndizovuta kwambiri pamapangidwe ophatikizira makina ophatikiza mipiringidzo ya laser diode.
2. Chiyambi Chathupi Chakusiyana
Divergence angle imatsimikiziridwa makamaka ndi mawonekedwe a waveguide ndi kukula kwa gawo lotulutsa:
Mu axis yofulumira, malo otulutsa mpweya ndi ochepa kwambiri. Malinga ndi chiphunzitso cha diffraction, timitsempha tating'onoting'ono timabweretsa kusiyana kwakukulu.
Mu axis pang'onopang'ono, mtengowo umakulirakulira motalika kwa bar kudutsa ma emitter angapo, zomwe zimapangitsa kuti pakhale mbali yaying'ono yosiyana.
Zotsatira zake, mipiringidzo ya laser diode mwachilengedwe imawonetsa kusiyanasiyana kwakukulu mumayendedwe othamanga komanso kutsika kotsika mumayendedwe oyenda pang'onopang'ono.
3. Momwe Divergence Angle Imakhudzira Mapangidwe Adongosolo
① Mtengo Wokwera Wophatikizana ndi Kupanga Beam
Chifukwa cha asymmetry yayikulu ya mtengo waiwisi, mawonekedwe a FAC (Fast Axis Collimation) ndi SAC (Slow Axis Collimation) ayenera kugwiritsidwa ntchito. Izi zimawonjezera zovuta zamakina ndipo zimafuna kukhazikika kwakukulu komanso kukhazikika kwamafuta.
② Kuchita Bwino Kwambiri kwa Fiber Coupling
Mukagwirizanitsa mipiringidzo ya laser mu multimode fibers, optical systems, kapena aspheric lens, kusiyana kwakukulu kwa axis kungayambitse "spillover," kuchepetsa kugwirizanitsa. Divergence ndiye gwero lalikulu la kuwonongeka kwa kuwala.
③ Ubwino wa Beam mu Module Stacking
M'ma module okhala ndi mipiringidzo yambiri, kusiyana kosayendetsedwa bwino kungayambitse kupindika kosagwirizana kapena kupotoza kwakutali, zomwe zimakhudza kuyang'ana kulondola komanso kugawa kwamafuta.
4. Momwe Mungalamulire ndi Kukonzekera Kusiyana mu Mabala a Laser Diode
Ngakhale kusiyana kumatanthauzidwa ndi kapangidwe ka chipangizocho, njira zingapo zamakina adongosolo zitha kugwiritsidwa ntchito kukhathamiritsa:
①Kugwiritsa ntchito ma lens a FAC
Kuyika lens yolumikizana mwachangu pafupi ndi mbali yotulutsa imakanikiza mtengo ndikuchepetsa kusiyanasiyana mu axis yothamanga-izi ndizofunikira pamapangidwe ambiri.
②Ma Lens a SAC Owonjezera Mapangidwe
Ngakhale kusiyana kwapang'onopang'ono kumakhala kocheperako, kuumba kumafunikabe motsatizana kapena magwero owunikira kuti akwaniritse zotsatira zofanana.
③Kuphatikizika kwa Beam ndi Optical Shaping Design
Kugwiritsa ntchito ma lens ang'onoang'ono, ma lens a cylindrical, kapena ma optics opangidwa amatha kuthandizira kuumba matabwa angapo a laser kuti akhale owala kwambiri, kutulutsa kofanana.
④Kukhathamiritsa kwa Waveguide pa Chipangizo
Kusintha makulidwe omwe amagwira ntchito, kapangidwe ka ma waveguide, ndi ma grating atha kuwongoleranso kusiyana kwa axis kuchokera pamlingo wa chip.
5. Divergence Control mu Real-World Applications
①Magwero Pampu Laser
M'makina amphamvu kwambiri olimba-state kapena fiber laser, mipiringidzo ya laser diode imakhala ngati magwero a pampu. Kuwongolera kusiyana-makamaka mu axis yothamanga-kumathandizira kulumikizana bwino komanso kuyang'ana kwa matabwa.
②Zida Zachipatala
Kwa machitidwe monga laser therapy ndi kuchotsa tsitsi, kuyang'anira kusiyana kumapangitsa kuti mphamvu zowonjezera zikhale zofanana komanso zotetezeka komanso zothandiza.
③Industrial Material Processing
Mu kuwotcherera kwa laser ndi kudula, kusiyanasiyana kokometsedwa kumathandizira kuti kachulukidwe wamagetsi apamwamba, kuyang'ana bwino, komanso kulondola, kukonza bwino.
6. Mapeto
Divergence angle ya laser diode bar ndi yofunika kwambiri kusintha - kuchokera ku micro-scale chip physics kupita ku macro-scale Optical system.
Zimagwira ntchito ngati chizindikiro cha mtengo wamtengo wapatali komanso malire apangidwe kuti agwirizane. Pamene zofuna za ntchito ndi zovuta za machitidwe zikupitirira kukwera, kumvetsetsa ndi kulamulira kusiyana kumakhala kofunika kwambiri kwa opanga laser ndi ophatikizana mofanana-makamaka kupita patsogolo ku mphamvu zapamwamba, kuwala, ndi kudalirika.
