Laser Diode Bar: The Core Power Kumbuyo kwa Mapulogalamu Akuluakulu a Laser

Pamene teknoloji ya laser ikupitirizabe kusintha, mitundu ya magwero a laser ikukhala yosiyana kwambiri. Pakati pawo, bala ya laser diode imadziwika chifukwa cha mphamvu zake zambiri, mawonekedwe ake ophatikizika, komanso kasamalidwe kabwino kamafuta, ndikupangitsa kuti ikhale gawo lofunikira m'magawo monga kukonza mafakitale, kukongola kwachipatala, magwero a mpope, ndi kafukufuku wasayansi.

1. Kodi Laser Diode Bar ndi chiyani?

Laser diode bar, yomwe imadziwikanso kuti laser diode array, ndi chipangizo champhamvu champhamvu cha semiconductor laser chomwe chimapangidwa pophatikiza ma unit angapo otulutsa laser pagawo limodzi wamba. Childs, aliyense wagawo emitting ndi za 100 micrometer m'lifupi, pamene okwana m'lifupi kapamwamba akhoza kuyambira angapo millimeters kuti centimita. Chifukwa mayunitsi angapo a laser amasanjidwa mbali ndi mbali, mipiringidzo ya laser diode imatha kupereka mphamvu mosalekeza kapena yosunthika kuchokera pa ma watts makumi ambiri kupita pa kilowati.

2. Zofunika Kwambiri

① Kachulukidwe Wamphamvu Kwambiri

Mipiringidzo ya laser diode imaphatikiza ma emitter angapo pamalo ophatikizika kuti apereke mphamvu zambiri, kuwapangitsa kukhala abwino kwa mapulogalamu omwe amafunikira mphamvu zambiri.

② Kuwongolera Kwabwino Kwambiri

Kapangidwe ka bar kameneka ndi kogwirizana ndi matekinoloje osiyanasiyana oyikamo, monga AuSn (golide-tin), all-indium, ndi ma hybrid ma CD, omwe amathandizira kutulutsa kutentha, kukulitsa moyo wa chipangizocho, ndikuwonetsetsa kugwira ntchito kwanthawi yayitali.

③ Ma Wavelengths Osinthika Mwamakonda anu

Kutengera kugwiritsa ntchito, mipiringidzo ya laser diode imatha kupangidwira mafunde osiyanasiyana ogwiritsira ntchito, monga 808 nm, 915 nm, 940 nm, ndi 976 nm. Kukonzekera kwapadera kwa kutalika kwa mafunde kumapezekanso kuti akwaniritse zosowa zenizeni za zipangizo ndi machitidwe osiyanasiyana.

④ Kusintha kwa Beam Yosinthika

Ngakhale mipiringidzo ya ma laser diode nthawi zambiri imakhala yotsika kuposa ma laser-mode-mode, zida zamagetsi monga ma lens arrays, fiber coupling, ndi ma micro-lens system zitha kugwiritsidwa ntchito kugwirizanitsa kapena kuyang'ana mtengowo, kupititsa patsogolo kuphatikiza ndi kusinthasintha pamakina ogwiritsira ntchito.

3. Minda Yofunsira

① Industrial Manufacturing

Amagwiritsidwa ntchito powotcherera pulasitiki, chithandizo cha kutentha kwachitsulo, kuyeretsa kwa laser, ndikuyika chizindikiro, mipiringidzo ya laser diode imapereka chiwongolero chamtengo wapatali pamakina omwe amafunikira magwero amphamvu kwambiri a laser.

② Zachipatala ndi Zokongoletsa

Mwachitsanzo, mipiringidzo ya 808 nm laser diode imagwiritsidwa ntchito kwambiri pazida zochotsa tsitsi la laser. Amapereka mphamvu zambiri komanso kuya kwapakati, kuwononga bwino ma follicle atsitsi popanda kuwononga minofu yozungulira.

③ Magwero a Pampu a Fiber Lasers

M'makina amphamvu kwambiri a fiber laser, mipiringidzo ya laser diode imagwiritsidwa ntchito ngati magwero a pampu kusangalatsa ulusi wa Yb-doped kapena Er-doped, kuchita gawo lofunika kwambiri pomanga makina amphamvu kwambiri a laser.

④ Kafukufuku wa Sayansi ndi Chitetezo

Mipiringidzo ya laser diode imagwiritsidwanso ntchito kwambiri muukadaulo wapamwamba monga kuyesa kwamphamvu kwambiri kwa sayansi yamagetsi, LiDAR, ndi kulumikizana kwa laser, chifukwa chakukhazikika kwawo komanso zomwe mungasinthe.

Pamene zofunikira za machitidwe a laser zikupitiriza kukwera, mipiringidzo ya laser diode ikupita ku mphamvu zapamwamba, kudalirika kwakukulu, mawonekedwe ang'onoang'ono, ndi kutsika mtengo. Monga gawo lofunikira pamakina ogwiritsira ntchito laser, mipiringidzo ya laser diode ikuvomerezedwa kwambiri m'magawo apamwamba kwambiri. Ndikupita patsogolo kwaukadaulo komanso kuchulukirachulukira kwamakampani, ma laser diode bar akuyembekezeka kusangalala ndi msika waukulu ndikutenga gawo lanzeru mtsogolo.
