Fiber Laser Nruam Thiab Pulsed, Yuav Xaiv Li Cas?

Fiber laser nrog nws cov qauv yooj yim, tsis tshua muaj nqi, siab electro-optical conversion efficiency, zoo tso zis, qhov kev faib ua feem ntawm industrial lasers yog nce txhua xyoo. Raws li kev txheeb cais, xyoo 2020, qhov feem ntawm fiber ntau lasers hauv kev lag luam laser tau mus txog 52.7%.
Muab faib los ntawm cov yam ntxwv ntawm cov teeb pom kev zoo, fiber ntau lasers tuaj yeem muab faib ua ob pawg: cov laser txuas ntxiv thiab cov laser pulsed. Dab tsi yog qhov kev sib txawv ntawm ob qho tib si, thiab cov ntawv thov twg yog qhov tsim nyog rau? Cov hauv qab no yog qhov sib piv luv luv ntawm qhov xwm txheej dav dav ntawm daim ntawv thov.
Raws li lub npe qhia, nruam fiber ntau laser tso zis laser yog tas mus li, lub hwj chim yog tswj nyob rau hauv ib tug taag theem, lub hwj chim no yog lub rated hwj chim ntawm lub laser. Lub zog no yog lub zog ntsuas ntawm lub laser. Qhov zoo ntawm cov fiber ntau txuas ntxiv yog nws txoj haujlwm ntev thiab ruaj khov.
Lub laser ntawm lub pulsed laser yog "intermittent". Tau kawg, lub sijhawm sib cuam tshuam no feem ntau luv luv, feem ntau hauv milliseconds, microseconds, lossis txawm nanoseconds lossis picoseconds. Piv nrog rau cov lasers tas mus li, qhov kev siv ntawm cov mem tes lasers yog nyob rau hauv tas li flux, li no lub tswvyim ntawm "peaks" thiab "troughs".
Los ntawm kev hloov pauv ntawm cov mem tes, lub laser pulsed tuaj yeem tso tawm sai sai, ncav cuag lub zog loj ntawm txoj haujlwm ncov, tab sis qhov nruab nrab lub zog yog qhov qis vim qhov muaj nyob ntawm lub trough. Nws tuaj yeem xav txog tias yog tias lub zog nruab nrab yog tib yam, ces lub ncov lub zog ntawm lub tshuab laser tuaj yeem loj dua li ntawm lub laser txuas ntxiv, paub txog lub zog ntau dua li ntawm lub laser txuas ntxiv, uas yog reflected hauv cov hlau. kev ua haujlwm, uas yog, nws muaj peev xwm nkag mus rau qhov tob ntawm kev nkag mus, thiab tib lub sijhawm, nws kuj tseem tsim nyog rau cov khoom siv hluav taws xob uas tsis tuaj yeem tiv taus cov cua sov, nrog rau qee cov khoom siv hluav taws xob zoo.
Los ntawm qhov tso zis hluav taws xob yam ntxwv ntawm ob, peb tuaj yeem txheeb xyuas qhov sib txawv ntawm daim ntawv thov.
Nruam fiber ntau laser feem ntau haum rau:
- Cov khoom siv loj ua, xws li tsheb thiab nkoj tshuab, steel phaj loj txiav ua, thiab lwm yam kev ua haujlwm uas tsis cuam tshuam rau cov teebmeem thermal, tab sis ntau dua rau tus nqi.
- Siv hauv kev kho mob rau kev phais txiav thiab coagulation, xws li tom qab phais hemostasis.
- Siv dav hauv fiber ntau optic kev sib txuas lus rau cov teeb liab kis tau tus mob thiab amplification nrog kev ruaj ntseg siab thiab tsis tshua muaj suab nrov.
- Siv rau hauv kev tshawb fawb tshawb fawb rau cov ntawv thov xws li kev tsom xam spectral, atomic physics thwmsim thiab LIDAR, muab lub zog siab thiab siab beam zoo laser tso zis.
Thaum pulsed fiber ntau lasers feem ntau haum rau:
- Kev ua tiav ntawm cov ntaub ntawv uas tsis tuaj yeem tiv taus qhov muaj zog thermal los yog nkig, xws li kev ua cov khoom siv hluav taws xob, cov iav ceramic, thiab cov khoom kho mob thiab cov khoom siv roj ntsha.
- Cov ntaub ntawv uas muaj kev cuam tshuam siab, yooj yim rau kev puas tsuaj rau lub taub hau laser nws tus kheej vim kev xav. Piv txwv li, kev ua cov khoom siv tooj liab thiab txhuas
- Kev kho deg lossis tu sab nrauv ntawm cov substrates yooj yim puas.
- Ua cov ntawv thov uas xav tau lub zog siab thiab nkag mus tob rau lub sijhawm luv luv, xws li txiav cov phaj tuab thiab xuas nrig ntaus qhov hauv cov ntaub ntawv hlau.
- Cov ntawv thov uas xav tau daim ntawv thov ntawm pulses raws li cov yam ntxwv teeb liab. Piv txwv li, fiber optic kev sib txuas lus thiab fiber optic sensors.
- Nyob rau hauv biomedical teb rau kev phais qhov muag, kev kho mob ntawm daim tawv nqaij, txiav cov ntaub so ntswg, thiab lwm yam., nrog siab beam zoo thiab modulation kev ua tau zoo.
- 3D luam ntawv rau siab precision thiab complex qauv ntawm hlau qhov chaw.
- Advanced Laser Riam phom
Muaj qee qhov sib txawv ntawm pulsed fiber ntau lasers thiab txuas txuas fiber ntau lasers raws li txoj cai, cov yam ntxwv thiab kev siv, thiab txhua qhov tsim nyog rau ntau zaus. Pulsed fiber ntau lasers yog tsim rau cov ntawv thov uas xav tau lub siab ncov lub zog thiab kev ua haujlwm ntawm kev hloov kho, xws li cov khoom siv thiab biomedicine; thaum nruam fiber ntau lasers yog haum rau daim ntaub ntawv uas yuav tsum tau muaj kev ruaj ntseg thiab siab beam zoo, xws li kev sib txuas lus thiab kev tshawb fawb. Xaiv qhov zoo ntawm fiber ntau laser rau koj cov kev xav tau tshwj xeeb yuav pab txhim kho kev ua haujlwm thiab daim ntawv thov zoo.
