Laser Diode Bar: Lub Hwj Chim Tseem Ceeb Tom Qab Cov Kev Siv Laser Muaj Zog Siab

Raws li cov thev naus laus zis laser txuas ntxiv mus, cov hom laser sources tau dhau los ua ntau haiv neeg. Ntawm lawv, lub laser diode bar sawv tawm rau nws cov zis hluav taws xob siab, cov qauv me me, thiab kev tswj hwm thermal zoo heev, ua rau nws yog ib qho tseem ceeb hauv cov teb xws li kev ua lag luam, kev kho mob zoo nkauj, cov twj tso kua mis, thiab kev tshawb fawb.

1. Lub Laser Diode Bar yog dab tsi?

Ib lub laser diode bar, tseem hu ua laser diode array, yog ib lub cuab yeej semiconductor laser muaj zog siab uas tsim los ntawm kev sib koom ua ke ntau lub laser-emitting units rau hauv ib lub substrate. Feem ntau, txhua lub emitting unit yog li 100 micrometers dav, thaum tag nrho qhov dav ntawm lub bar tuaj yeem ntau ntawm ob peb millimeters mus rau centimeters. Vim tias ntau lub laser units tau teeb tsa ua ke, laser diode bars tuaj yeem xa cov zog txuas ntxiv lossis pulsed los ntawm kaum tawm watts mus rau ntau dua ib kilowatt.

2. Cov yam ntxwv tseem ceeb

① Lub zog ceev ceev

Cov kab laser diode sib xyaw ua ke ntau lub emitters hauv qhov chaw me me kom xa hluav taws xob siab heev, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau hluav taws xob ntau.

② Kev Tswj Xyuas Thermal Zoo heev

Cov qauv ntawm lub bar no sib xws nrog ntau yam thev naus laus zis ntim khoom, xws li AuSn (kub-tin), all-indium, thiab hybrid ntim khoom, uas ua rau kom cov cua sov tawm zoo dua, ua kom lub cuab yeej siv tau ntev dua, thiab ua kom ruaj khov rau kev ua haujlwm ntev.

③ Cov Wavelengths uas hloov kho tau

Nyob ntawm daim ntawv thov, cov kab laser diode tuaj yeem tsim rau ntau qhov wavelengths ua haujlwm, xws li 808 nm, 915 nm, 940 nm, thiab 976 nm. Kev hloov kho wavelength tshwj xeeb kuj muaj los ua kom tau raws li qhov xav tau tshwj xeeb ntawm ntau yam khoom siv thiab cov kab ke.

④ Kev Tsim Qauv Beam Yooj Yim

Txawm hais tias qhov zoo ntawm cov kab teeb laser diode feem ntau qis dua li ntawm cov lasers ib hom, cov khoom siv kho qhov muag xws li cov lens arrays, fiber coupling, thiab micro-lens systems tuaj yeem siv los sib sau ua ke lossis tsom mus rau lub teeb, txhim kho kev koom ua ke thiab kev ywj pheej hauv kev siv system.

3. Cov Ntawv Thov

① Kev Tsim Khoom Lag Luam

Siv rau hauv kev vuam yas, kev kho cua sov hlau, kev ntxuav laser, thiab kev cim, cov kab laser diode muab cov nqi zoo heev hauv cov kab ke uas xav tau cov peev txheej laser muaj zog siab.

② Kev Kho Mob thiab Kev Zoo Nkauj

Piv txwv li, 808 nm laser diode bars yog siv dav hauv cov khoom siv laser tshem tawm cov plaub hau. Lawv muab lub zog siab thiab nkag mus tob, ua rau cov plaub hau puas tsuaj yam tsis ua rau cov ntaub so ntswg nyob ib puag ncig puas tsuaj.

③ Cov Twj Tso Kua Mis rau Fiber Lasers

Hauv cov tshuab laser fiber ntau muaj zog, cov laser diode bars feem ntau siv ua cov twj tso kua mis los txhawb Yb-doped lossis Er-doped fibers, ua lub luag haujlwm tseem ceeb hauv kev tsim cov tshuab laser muaj zog.

④ Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Tiv Thaiv

Cov kab laser diode kuj tseem siv dav hauv cov thev naus laus zis siab heev xws li kev sim physics siab zog, LiDAR, thiab kev sib txuas lus laser, vim lawv cov zis ruaj khov thiab cov khoom hloov kho tau.

Raws li qhov yuav tsum tau ua haujlwm rau cov tshuab laser txuas ntxiv nce siab, cov laser diode bars tab tom hloov zuj zus mus rau lub zog siab dua, kev ntseeg siab dua, cov qauv me dua, thiab cov nqi qis dua. Raws li ib qho tseem ceeb hauv cov txheej txheem siv laser, cov laser diode bars tau raug siv dav thoob plaws hauv cov teb high-tech. Nrog rau kev nce qib ntawm thev naus laus zis thiab kev lag luam loj hlob zuj zus, cov laser diode bars yuav txaus siab rau kev lag luam dav dua thiab ua lub luag haujlwm tseem ceeb dua yav tom ntej.
