Pamene ukadaulo wa laser ukupitirirabe kusintha, mitundu ya magwero a laser ikusiyana kwambiri. Pakati pawo, bala ya laser diode imadziwika ndi mphamvu zake zambiri, kapangidwe kake kakang'ono, komanso kayendetsedwe kabwino ka kutentha, zomwe zimapangitsa kuti ikhale gawo lofunikira kwambiri m'magawo monga kukonza mafakitale, kukongola kwa zamankhwala, magwero a mapampu, ndi kafukufuku wasayansi.
1. Kodi Laser Diode Bar ndi chiyani?
Chida cha laser diode, chomwe chimadziwikanso kuti laser diode array, ndi chipangizo cha laser champhamvu kwambiri chomwe chimapangidwa pophatikiza mayunitsi angapo otulutsa laser pa substrate imodzi yodziwika bwino. Kawirikawiri, chipangizo chilichonse chotulutsa mpweya chimakhala ndi maikromita 100 m'lifupi, pomwe m'lifupi mwake mutha kuyambira mamilimita angapo mpaka masentimita. Chifukwa mayunitsi angapo a laser amakonzedwa mbali imodzi, ma laser diode bar amatha kupereka mphamvu yopitilira kapena yothamanga kuyambira ma watts makumi ambiri mpaka kilowatt yoposa imodzi.
2. Zinthu Zofunika Kwambiri
① Mphamvu Yaikulu Yopangira Mphamvu
Mipiringidzo ya laser diode imagwirizanitsa ma emitter angapo m'malo ochepa kuti apereke mphamvu zambiri, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zomwe zimafuna mphamvu zambiri.
② Kusamalira bwino kutentha
Kapangidwe ka bala kamagwirizana ndi ukadaulo wosiyanasiyana wopaka, monga AuSn (golide-tin), all-indium, ndi ma paketi osakanizidwa, zomwe zimapangitsa kuti kutentha kusatenthe, kutalikitsa nthawi ya chipangizocho, ndikuwonetsetsa kuti chikugwira ntchito bwino kwa nthawi yayitali.
③ Mafunde Osinthika
Kutengera ndi momwe zimagwiritsidwira ntchito, mipiringidzo ya laser diode ikhoza kupangidwira mafunde osiyanasiyana ogwirira ntchito, monga 808 nm, 915 nm, 940 nm, ndi 976 nm. Kusintha kwapadera kwa mafunde kuliponso kuti kukwaniritse zosowa za zipangizo ndi machitidwe osiyanasiyana.
④ Kupanga Mtengo Wosinthasintha
Ngakhale kuti ubwino wa kuwala kwa laser diode bar nthawi zambiri umakhala wotsika kuposa wa single-mode lasers, zigawo zowunikira monga ma lens arrays, fiber coupling, ndi micro-lens systems zingagwiritsidwe ntchito kulumikiza kapena kuyang'ana kuwalako, zomwe zimapangitsa kuti kuphatikizana ndi kusinthasintha kwa ntchito zamakina kukhale kothandiza.
3. Minda Yogwiritsira Ntchito
① Kupanga Mafakitale
Mipiringidzo ya laser diode yomwe imagwiritsidwa ntchito polumikiza pulasitiki, kuchiza kutentha kwachitsulo, kuyeretsa ndi kuyika chizindikiro pa laser, imapereka chiŵerengero chabwino kwambiri cha mtengo ndi magwiridwe antchito m'makina omwe amafunikira magwero amphamvu a laser.
② Zachipatala ndi Zokongola
Mwachitsanzo, mipiringidzo ya laser diode ya 808 nm imagwiritsidwa ntchito kwambiri muzipangizo zochotsera tsitsi za laser. Zimapereka mphamvu zambiri komanso kuzama pang'ono, zomwe zimawononga bwino ma follicle a tsitsi popanda kuwononga minofu yozungulira.
③ Magwero a Pampu a Laser ya Ulusi
Mu makina a laser amphamvu kwambiri, mipiringidzo ya laser diode nthawi zambiri imagwiritsidwa ntchito ngati magwero a mapampu kuti asangalatse ulusi wopangidwa ndi Yb kapena Er, zomwe zimathandiza kwambiri popanga makina a laser amphamvu kwambiri.
④ Kafukufuku wa Sayansi ndi Chitetezo
Mipiringidzo ya laser diode imagwiritsidwanso ntchito kwambiri muukadaulo wapamwamba monga kuyesa kwa fizikisi yamphamvu kwambiri, LiDAR, ndi kulumikizana kwa laser, chifukwa cha kutulutsa kwawo kokhazikika komanso mawonekedwe ake osinthika.
Pamene zofunikira pakugwira ntchito kwa makina a laser zikupitirira kukwera, mipiringidzo ya laser diode ikusintha kukhala mphamvu yapamwamba, kudalirika kwakukulu, mawonekedwe ang'onoang'ono, komanso ndalama zochepa. Monga gawo lofunikira kwambiri mumakina ogwiritsira ntchito laser, mipiringidzo ya laser diode ikugwiritsiridwa ntchito kwambiri m'magawo apamwamba aukadaulo. Ndi kupita patsogolo kwaukadaulo komanso unyolo wamakampani womwe ukukulirakulira, mipiringidzo ya laser diode ikuyembekezeka kukhala ndi mwayi waukulu pamsika ndikutenga gawo lanzeru mtsogolo.
