Chiyambi

Ndi kupita patsogolo mwachangu mu chiphunzitso cha semiconductor laser, zipangizo, njira zopangira, ndi ukadaulo wolongedza, pamodzi ndi kusintha kosalekeza kwa mphamvu, magwiridwe antchito, ndi moyo, ma laser amphamvu kwambiri a semiconductor akugwiritsidwa ntchito kwambiri ngati magwero a kuwala mwachindunji kapena kupompa. Ma laser awa sagwiritsidwa ntchito kwambiri pokonza laser, chithandizo chamankhwala, ndi ukadaulo wowonetsera komanso ndi ofunikira kwambiri polankhulana ndi kuwala kwa mlengalenga, kuzindikira kwa mlengalenga, LIDAR, ndi kuzindikira cholinga. Ma laser amphamvu kwambiri ndi ofunikira kwambiri pakukula kwa mafakitale angapo apamwamba ndipo amayimira mpikisano pakati pa mayiko otukuka.

Laser Yopangidwa ndi Semiconductor Yokhala ndi Ma Stacked Array Yokhala ndi Fast-Axis Collimation

Monga magwero apakati a pampu ya ma laser a solid-state ndi fiber, ma laser a semiconductor amawonetsa kusintha kwa wavelength kupita ku red spectrum pamene kutentha kwa ntchito kukukwera, nthawi zambiri ndi 0.2-0.3 nm/°C. Kusuntha kumeneku kungayambitse kusalingana pakati pa mizere yotulutsa ya ma LD ndi mizere yoyamwa ya solid gain media, kuchepetsa coefficient ya kuyamwa ndikuchepetsa kwambiri mphamvu ya laser output. Nthawi zambiri, machitidwe ovuta owongolera kutentha amagwiritsidwa ntchito kuziziritsa ma laser, zomwe zimawonjezera kukula kwa makina ndi kugwiritsa ntchito mphamvu. Pofuna kukwaniritsa zosowa za miniaturization mu ntchito monga autonomous driving, laser ranging, ndi LIDAR, kampani yathu yayambitsa multi-peak, conductively cooled stacked array series LM-8xx-Q4000-F-G20-P0.73-1. Mwa kukulitsa kuchuluka kwa mizere yotulutsa ya LD, mankhwalawa amasunga kuyamwa kokhazikika ndi solid gain medium pamlingo wokulirapo wa kutentha, kuchepetsa kupsinjika kwa makina owongolera kutentha ndikuchepetsa kukula kwa laser ndi kugwiritsa ntchito mphamvu pamene akutsimikizira kutulutsa mphamvu zambiri. Pogwiritsa ntchito njira zoyesera za bare chip, vacuum coalescence bonding, interface material ndi fusion engineering, komanso transient thermal management, kampani yathu ikhoza kukwaniritsa kulamulira kolondola kwa multi-peak, kugwira ntchito bwino kwambiri, kuyang'anira kutentha kwapamwamba, ndikuwonetsetsa kuti zinthu zathu zotsatizana zikukhala zodalirika kwa nthawi yayitali komanso zamoyo.

Zinthu Zamalonda

Kutulutsa kwa Multi-Peak Kolamulidwa Monga gwero la mapampu a ma laser olimba, chinthu chatsopanochi chidapangidwa kuti chikulitse kutentha kokhazikika komanso kupangitsa kuti makina oyendetsa kutentha a laser akhale osavuta pakati pa zomwe zikuchitika pakupanga ma laser a semiconductor. Ndi makina athu apamwamba oyesera a bare chip, titha kusankha molondola mafunde a bar chip ndi mphamvu, zomwe zimathandiza kulamulira mafunde a chipangizocho, malo otalikirana, ndi mafunde angapo owongolera (≥2 peaks), zomwe zimakulitsa kutentha komwe kumagwira ntchito ndikukhazikitsa kuyamwa kwa pampu.

Kupsinjika kwa Mzere Wofulumira

Chogulitsachi chimagwiritsa ntchito magalasi ang'onoang'ono owonera kuti azitha kukanikiza mwachangu, kusintha ngodya ya fast-axis divergence malinga ndi zofunikira zina kuti awonjezere ubwino wa kuwala. Dongosolo lathu la fast-axis online collimation limalola kuyang'anira ndikusintha nthawi yeniyeni panthawi yokanikiza, kuonetsetsa kuti mawonekedwe a malo akusintha bwino malinga ndi kusintha kwa kutentha kwa chilengedwe, ndi kusintha kwa <12%.

Kapangidwe ka Modular

Chogulitsachi chimaphatikiza kulondola ndi kugwiritsa ntchito bwino pakupanga kwake. Chodziwika ndi mawonekedwe ake opapatiza komanso osavuta kugwiritsa ntchito, chimapereka kusinthasintha kwakukulu pakugwiritsa ntchito kwenikweni. Kapangidwe kake kolimba, kolimba komanso zinthu zodalirika kwambiri zimathandizira kuti ntchito yake ikhale yokhazikika kwa nthawi yayitali. Kapangidwe ka modular kamalola kusintha kosinthika kuti kakwaniritse zosowa za makasitomala, kuphatikiza kusintha kwa kutalika kwa nthawi, malo otulutsa mpweya, ndi kukanikiza, zomwe zimapangitsa kuti chinthucho chikhale chosinthika komanso chodalirika.

Ukadaulo Woyang'anira Kutentha

Pa chinthu cha LM-8xx-Q4000-F-G20-P0.73-1, timagwiritsa ntchito zipangizo zotenthetsera kutentha kwambiri zomwe zimagwirizana ndi CTE ya bala, kuonetsetsa kuti zinthuzo zikugwirizana komanso kutentha bwino. Njira zomaliza zimagwiritsidwa ntchito poyesa ndikuwerengera mphamvu ya kutentha ya chipangizocho, kuphatikiza bwino ma simulation a kutentha osinthasintha komanso okhazikika kuti azitha kuwongolera bwino kusintha kwa kutentha.

Kuwongolera Njira Chitsanzochi chimagwiritsa ntchito ukadaulo wachikhalidwe wowotcherera wolimba. Kudzera mu njira yowongolera, chimatsimikizira kutentha bwino mkati mwa malo omwe akhazikitsidwa, osati kungosunga magwiridwe antchito a chinthucho komanso kuonetsetsa kuti chili chotetezeka komanso cholimba.

Zofotokozera Zamalonda

Chogulitsachi chili ndi mafunde otha kulamulira okhala ndi mafunde ambiri, kukula kochepa, kulemera kopepuka, mphamvu yosinthira yamagetsi, kudalirika kwambiri, komanso moyo wautali. Laser yathu yaposachedwa ya multi-peak semiconductor stacked array bar, monga multi-peak semiconductor laser, imatsimikizira kuti kutalika kulikonse kwa mafunde kumawoneka bwino. Ikhoza kusinthidwa molondola malinga ndi zosowa za makasitomala malinga ndi zosowa za mafunde, malo, kuchuluka kwa mafunde, ndi mphamvu yotulutsa, kuwonetsa mawonekedwe ake osinthika. Kapangidwe ka modular kamasinthasintha malinga ndi malo osiyanasiyana ogwiritsira ntchito, ndipo kuphatikiza ma module osiyanasiyana kumatha kukwaniritsa zosowa zosiyanasiyana za makasitomala.
