Hauv kev tsim cov txheej txheem ntawm laser vuam siv tshuab, laser yog sib npaug rau kev txiab hauv cov txheej txheem laser welding. Txoj kev sib koom ua ke zoo tshaj plaws ntawm ob qho khoom yog ua tiav los ntawm laser kis. Nws tuaj yeem hais tias yog tsis muaj laser, yuav tsis muaj kev tsim cov khoom siv laser vuam siv. Hauv lwm lo lus, raws li ib tus neeg ua haujlwm ntawm thaj chaw ntawm laser welding, koj paub ntau npaum li cas txog kev txhim kho ntawm laser?
Semiconductor lasers yog siv dav
Rov qab rau xyoo 1980, semiconductor lasers tsuas yog siv hauv kev khaws cia kho qhov muag thiab qee qhov kev siv niche. Lub sijhawm ntawd, kev khaws cia kho qhov muag tau yog thawj daim ntawv sau npe loj hauv kev lag luam semiconductor laser. Nrog cov kev tsim kho tas mus li ntawm semiconductor laser thev naus laus zis, kev txhim kho ntawm cov thev naus laus zis cia siv tshuab, xws li kev txhaj tshuaj digital multi-functional disc (DVD) thiab xiav lub teeb disc (BD), tau nce qib. Los ntawm 1980s, kho qhov muag network tau dhau los ua qhov sib ntaus sib tua tseem ceeb ntawm semiconductor lasers. Tom qab ntawd, semiconductor laser tau dhau los ua cov txheej txheem tseem ceeb thiab kev tsim khoom ntawm kev sib txuas lus network.
Vim tias qhov zoo ntawm cov khoom lag luam yooj yim, cov khoom lag luam yooj yim ntau lawm, tus nqi qis, kev siv dav dav dav, lub neej me me, lub neej ntev, kev siv hluav taws xob tsawg, kev ua haujlwm siab ntawm electro-optic hloov dua siab tshiab, semiconductor lasers tau siv dav hauv CD laser disc player, optical kev sib txuas lus fiber ntau, cim xeeb pom zoo, laser tshuab luam ntawv, thiab lwm yam, thiab maj mam npog cov tswv yim kev ua lag luam ntawm ntau cov teb optoelectronics. Nrog kev txhim kho ntawm cov zis hluav taws xob thiab cov yam ntxwv ntawm cov tshuab hluav taws xob ntau, nws tau maj mam pib ua lub luag haujlwm ntawm kev tsim khoom lag luam. Ntxiv rau kev koom nrog ncaj qha rau hauv kev tsim khoom lag luam, semiconductor lasers yog siv ntau dua li cov twj tso kua mis los rau cov khoom lag luam fiber ntau thiab cov teeb meem khov kho-xeev. Lawv tsim ua ke nrog kev lag luam laser kev lag luam thiab usher hauv cov ntsiab lus kev loj hlob tshiab nrog kev tawm ntawm cov lasers fiber ntau.
Vim tias cov kev txwv ntawm lub nqaj zoo, cov khoom siv hluav taws xob semiconductor lasers nyuaj rau siv ncaj qha rau hauv kev txiav hlau. Xyoo tsis ntev los no, nrog kev txhim kho ntawm cov roj hmab txuas txuas nrog cov thev naus laus zis thiab kev paub tab tiav kev loj hlob ntawm cov nqaj sib txuas tshiab thev naus laus zis, qee qhov semiconductor lasers nrog cov zis tso tawm saum kilowatt qib kuj tseem tuaj yeem ua tau raws li cov kev cai ntawm kev txiav nqaj zoo. Ntxiv rau, vim muaj ntau haiv neeg ntawm cov khoom siv hluav taws xob laser wavelength, luv luv wavelength semiconductor laser ze heev rau qhov siab tshaj plaws wavelength nqus ntawm txhuas. Yog li ntawd, hauv kev lag luam tsheb, muaj lub tshuab hluav taws xob ntau lub tshuab hluav taws xob laser yog qhov tsim nyog rau txhuas lub cev tsheb vuam siv. Tam sim no, semiconductor laser nrog cov zis hluav taws xob ntawm 2kW thiab 6kW tau siv dav hauv kev lag luam tsheb.
Hauv thaj teb ntawm cov khoom siv ncaj qha kev coj ua, cov nqaj zoo ntawm cov khoom siv hluav taws xob semiconductor laser yog nyuaj rau kev tshaj ntawd cov fiber ntau laser, tab sis nws yog qhov haum rau nyias phaj vuam thiab txiav daim ntawv thov. Txoj kev txhim kho ntawm lub zog hluav taws xob semiconductor laser ua rau ntau cov ntawv thov tseem ceeb. Ntxiv rau kev siv raws li kev lag luam laser twj tso kua mis thiab cov khoom lag luam ncaj qha, phaj ua thiab luam ntawv, kev kho mob cosmetology thiab teeb pom kev zoo tau dhau los ua cov ntawv thov tseem ceeb ntawm kev lag luam semiconductor lasers.
