Lub neej yav tom ntej ntawm Semiconductor Lasers yog dab tsi?

Semiconductor LasersFeem ntau hu ua laser diodes vim lawv siv cov khoom siv semiconductor ua cov khoom ua haujlwm, yog li lawv hu ua semiconductor lasers. Semiconductor lasers feem ntau siv cov ntaub ntawv ua haujlwm xws li gallium arsenide, cadmium sulfide, indium phosphide, thiab lwm yam, uas tuaj yeem siv los ua cov twj tso kua mis rau fiber ntau lasers thiab cov khoom lasers, lossis tuaj yeem tso tawm ncaj qha laser raws li lub teeb ci.

Raws li kev lag luam kev lag luam hloov pauv thiab hloov kho mus rau qib siab thiab kev txawj ntse, cov khoom siv laser ua cov ntawv thov kev lag luam txuas ntxiv nthuav dav. Moore, ib tus tsim ntawm Moore Txoj Cai, tau kwv yees xyoo 1965 tias cov khoom siv hluav taws xob yuav txhim kho sai, thiab cov khoom siv hluav taws xob yuav tau txais kev nrov nrov thiab nkag mus rau ntau yam ntawm daim ntawv thov. Saib rov qab ib nrab xyoo tom qab, qhov kev twv ua ntej no tau lees paub zoo kawg nkaus. Txawm hais tias fiber ntau lasers muaj peev xwm ua lag luam zoo vim lawv qhov zoo, semiconductor lasers yog tam sim no siv dav hauv kev ua lag luam.

Txoj kev loj hlob ntawm semiconductor lasers pib nyob rau hauv 1960s thiab tam sim no tau lug txhawb thiab siv nyob rau hauv tag nrho cov mus rau lub neej. Nrog rau qhov zoo ntawm cov qauv compact, zoo nqaj zoo, lub neej ntev thiab kev ua haujlwm ruaj khov, nws tau siv dav hauv kev sib txuas lus, kev tsim khoom thiab kev tsim khoom, tub rog, kev kho mob thiab lwm yam kev lag luam. Precisely vim hais tias cov khoom siv laser muaj ntau yam kev siv thiab muaj ntau yam lag luam, kev lag luam loj ntawm semiconductor lasers loj heev. Raws li OFweek kev lag luam kev tshawb fawb cov ntaub ntawv, kev lag luam loj ntawm semiconductor lasers nyob rau hauv 2017 mus txog US $ 5.31 billion, nrog rau ib xyoo-rau-xyoo txoj kev loj hlob ntawm 15%, accounting rau 40% ntawm tag nrho cov laser lag luam qhia, thiab yog ib qho tseem ceeb txoj hauj lwm. .

Kev txhim kho technology thiab daim ntawv thov teb txuas ntxiv
Nrog rau kev txhim kho txuas ntxiv hauv qhov tob ntawm semiconductor thev naus laus zis, kev lag luam xav tau txuas ntxiv mus. Daim ntawv thov teb ntawm semiconductor lasers kuj hloov tas li. Los ntawm thawj cov khoom siv hluav taws xob qis rau cov cuab yeej siv hluav taws xob siab tam sim no, semiconductor lasers kuj tau txav los ntawm qee qhov chaw ua haujlwm lub teeb mus rau qhov ua haujlwm hnyav.

Raws li thaum ntxov xyoo 1980s, semiconductor lasers tsuas yog siv nyob rau hauv kho qhov muag cia thiab qee qhov kev siv niche. Thaum lub sij hawm, optical cia yog lub semiconductor laser kev lag luam thawj daim ntawv thov loj. Lub nruam innovation ntawm semiconductor laser technology tau txhawb txoj kev loj hlob ntawm optical cia technologies xws li cov ntau yam discs (DVD) thiab xiav-duab tshav discs (BD). Los ntawm xyoo 1990, optical networks tau dhau los ua qhov kev sib ntaus sib tua tseem ceeb rau semiconductor lasers. Tom qab xyoo 1990, semiconductor lasers tau los ua cov khoom tseem ceeb thiab tsim khoom rau kev sib txuas lus.

Tam sim no, daim ntawv thov loj tshaj plaws ntawm semiconductor lasers yog lub twj tso kua mis rau fiber ntau lasers thiab solid-state lasers. Thaum lub tshuab hluav taws xob semiconductor siv los ua fiber ntau laser twj tso kua mis, cov qauv ntawm lub twj tso kua mis tuaj yeem yooj yim yooj yim thiab lub twj tso kua mis lub zog tuaj yeem nce los ntawm kev ua kom lub zog ntawm lub zog. Raws li fiber ntau lasers thiab solid-state lasers muaj kev xav tau ntau dua rau cov zis hluav taws xob, cov kev xav tau siab dua kuj tau muab tso rau ntawm lub zog ntawm semiconductor twj tso kua mis.

Vim qhov kev txwv ntawm cov nqaj zoo, cov tsoos semiconductor lasers yog qhov nyuaj rau kev siv ncaj qha rau hlau txiav. Nyob rau hauv xyoo tas los no, nrog kev txhim kho ntawm semiconductor coupling technology thiab maj mam loj hlob ntawm cov nqaj tshiab combining thev naus laus zis, qee qhov fiber ntau tso tawm semiconductor lasers nrog ib kilowatt lossis qib siab dua tuaj yeem ua tau raws li qhov yuav tsum tau ua kom zoo rau kev txiav. Tsis tas li ntawd, vim muaj ntau haiv neeg ntawm semiconductor laser wavelengths, lub wavelength ntawm luv luv wavelength semiconductor lasers yog ze heev rau lub wavelength absorption siab tshaj plaws ntawm txhuas. Yog li ntawd, nyob rau hauv kev lag luam automotive, high-power semiconductor lasers yog heev haum rau vuam aluminium tsheb lub cev. Tam sim no, semiconductor lasers nrog laser tso zis powers ntawm 2KW thiab 6KW tau dav siv nyob rau hauv cov txheej txheem ntau lawm ntawm kev lag luam tsheb.

Nyob rau hauv lub tshav pob ntawm cov khoom siv ncaj qha, cov nqaj zoo ntawm semiconductor lasers yog qhov nyuaj rau tshaj li ntawm fiber ntau lasers. Txawm li cas los xij, semiconductor lasers yog qhov tsim nyog rau nyias phaj vuam thiab txiav daim ntawv thov. Txoj kev loj hlob ntawm high-power semiconductor lasers tau ua ntau yam kev siv tseem ceeb. Cov lasers no tau hloov ntau yam kev siv thev naus laus zis thiab coj peb ntau yam khoom tshiab.

Kev txhim kho yav tom ntej ntawm semiconductor lasers feem ntau suav nrog cov hauv qab no:
Thawj yog lub zog siab. Nrog rau kev nce qib hauv cov ntaub ntawv sib txuas hauv network, kev sib txuas lus xav tau ntau dua lub zog lasers kom xa cov teeb liab kho qhov muag thiab ua tiav cov ntaub ntawv xa mus nrawm dua. Nyob rau tib lub sijhawm, lasers siab dua kuj tseem xav tau hauv kev tsim khoom, kev ua laser thiab lwm yam kev lag luam los txhim kho kev tsim khoom thiab zoo.
Qhov thib ob yog miniaturization. Nrog rau txoj kev loj hlob sai ntawm cov khoom siv sib txuas lus txawb, kev sib txuas lus kho qhov muag thiab lwm yam kev lag luam, qhov yuav tsum tau ua rau qhov loj ntawm semiconductor lasers tau txais me me thiab me, thiab miniaturization thiab kev koom ua ke yuav tsum tau maj mam ua tiav. Qhov no tsis tsuas yog txo lub nra ntawm cov khoom siv, tab sis kuj txo cov nqi tsim khoom.
Qhov thib peb yog multi-functionality. Cov ntawv thov niaj hnub no xav tau cov khoom siv laser hloov tau yooj yim dua uas tuaj yeem hloov tau rau ntau lub sijhawm. Yog li ntawd, kev lag luam semiconductor laser yuav muaj ntau daim ntawv thov nyob rau hauv multimedia, kev ntsuam xyuas ib puag ncig, kev tshawb fawb txog lub neej thiab lwm yam.
Qhov thib plaub yog lub zog efficiency. Qhov siab dua lub zog efficiency ntawm semiconductor lasers, lub zog tsawg lawv yuav siv. Qhov no tsis tuaj yeem pab txo qis tib neeg kev cuam tshuam hauv ntiaj teb, tab sis kuj txo cov nqi lag luam, txhim kho kev lag luam muaj zog, thiab txhim kho kev lag luam kev sib tw.

Feem ntau hais lus, vim kev txhim kho txuas ntxiv ntawm thev naus laus zis, daim ntawv thov kev lag luam ntawm semiconductor lasers tau hloov tas li, thiab cov kev hloov no tseem tshwm sim. Feem ntau hais lus, semiconductor lasers tab tom txhim kho rau luv emission wavelengths thiab ntau dua emission powers hloov mus rau tam sim no kev lag luam xav tau.
