Lub neej yav tom ntej ntawm Semiconductor Lasers nyob qhov twg?

Nrog rau kev hloov pauv thiab kho dua tshiab ntawm kev tsim khoom lag luam mus rau qib siab thiab kev txawj ntse, cov khoom siv laser ua daim ntawv thov kev lag luam txuas ntxiv nthuav dav. Moore, ib tug ntawm cov tsim ntawm Moore Txoj Cai, kwv yees xyoo 1965 tias cov khoom siv hluav taws xob yuav loj hlob sai, thiab cov khoom siv hluav taws xob yuav tau txais kev nrov nrov thiab nkag mus rau ntau yam kev siv. 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, feem ntau siv semiconductor lasers tam sim no nyob rau hauv kev ua lag luam.

Semiconductor lasers feem ntau hu ua laser diodes. Vim nws cov yam ntxwv ntawm kev siv cov khoom siv semiconductor ua cov khoom ua haujlwm, nws hu ua semiconductor lasers. Cov khoom siv ua haujlwm feem ntau yog siv hauv semiconductor lasers yog gallium arsenide, cadmium sulfide, indium phosphide, thiab lwm yam, uas tuaj yeem siv los ua lub twj tso kua mis rau fiber ntau lasers thiab solid-state lasers, thiab tuaj yeem ncaj qha tso zis laser raws li lub teeb ci.

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 ua haujlwm zoo hauv kev sib txuas lus, kev tsim khoom thiab kev tsim khoom, tub rog, kev kho mob thiab lwm yam kev lag luam. Nws yog qhov tseeb vim tias daim ntawv thov teb ntawm cov khoom siv laser yog dav heev thiab koom nrog ntau qhov kev lag luam, yog li kev lag luam loj ntawm semiconductor lasers loj heev. Raws li cov ntaub ntawv ntawm OFweek kev lag luam kev tshawb fawb, kev lag luam loj ntawm semiconductor lasers nyob rau hauv 2017 yog siab li 5.31 billion US dollars, nrog rau ib xyoo-rau-xyoo kev loj hlob tus nqi nce mus txog 15%, tuav 40% ntawm tag nrho cov lag luam feem ntawm. lasers, uas yog ib qho tseem ceeb ntawm txoj hauj lwm.

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 tam sim no, semiconductor lasers kuj tau raug xa mus 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 sijhawm, optical cia yog thawj daim ntawv thov loj hauv kev lag luam semiconductor laser. Lub nruam innovation ntawm semiconductor laser technology tau txhawb txoj kev loj hlob ntawm optical cia technologies xws li txhaj tshuaj digital multifunction disc (DVD) thiab Blu-duab tshav Disc (BD). Los ntawm 1990s, optical networks tau dhau los ua qhov kev sib ntaus sib tua tseem ceeb rau semiconductor lasers. Tom qab ntawd 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 semiconductor laser siv los ua lub twj tso kua mis ntawm fiber ntau laser, cov qauv ntawm lub twj tso kua mis tuaj yeem ua kom yooj yim los ntawm kev txhim kho lub zog ntawm chav tsev, thiab lub twj tso kua mis lub zog tuaj yeem txhim kho. Nrog rau kev tsim hluav taws xob ntau ntxiv ntawm fiber ntau lasers thiab solid-state lasers, lub zog ntawm semiconductor twj tso kua mis kuj tau muab tso rau hauv kev xav tau ntau dua.

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 txuas thev naus laus zis thiab kev loj hlob zuj zus ntawm cov kab hluav taws xob tshiab sib txuas thev naus laus zis, qee qhov semiconductor lasers nrog fiber ntau tso tawm siab tshaj qib kilowatt kuj tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm cov nqaj zoo rau kev txiav. Tsis tas li ntawd, vim muaj ntau haiv neeg ntawm lub wavelength ntawm lub semiconductor laser, lub wavelength ntawm lub luv luv wavelength semiconductor laser yog ze heev rau lub siab tshaj plaws wavelength absorption ntawm txhuas. Yog li ntawd, nyob rau hauv kev lag luam automotive, high-power semiconductor lasers yog heev haum rau welding aluminium tsheb lub cev. Tam sim no, semiconductor lasers nrog laser tso zis zog ntawm 2KW thiab 6KW tau dav siv nyob rau hauv cov txheej txheem ntawm kev lag luam automotive.

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, nyob rau hauv nyias phaj vuam thiab txiav daim ntaub ntawv, semiconductor lasers yog heev haum. 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 tau muab ntau yam khoom tshiab rau peb.
