Siv rau xaiv ib hom fiber ntau laser

Siv rau kev xaivib hom fiber ntau laser
Hauv kev siv cov tswv yim, xaiv ib hom kev tsim nyogfiber ntau laseryuav tsum muaj lub cev hnyav ntawm ntau yam kev ntsuas los xyuas kom meej tias nws qhov kev ua tau zoo sib xws rau cov ntawv thov tshwj xeeb, ib puag ncig kev ua haujlwm thiab kev txwv nyiaj txiag. Tshooj lus no yuav muab cov txheej txheem xaiv cov tswv yim raws li qhov yuav tsum tau ua.
Kev xaiv lub tswv yim raws li daim ntawv thov scenarios
Cov kev xav tau rau kev ua haujlwmlaserssib txawv heev nyob rau txawv daim ntawv thov scenarios. Thawj kauj ruam hauv kev xaiv yog kom qhia meej cov ntsiab lus tseem ceeb ntawm daim ntawv thov.
Precision cov khoom ua thiab micro-nano manufacturing: Cov ntawv thov xws li kev txiav npluav, drilling, semiconductor wafer dicing, micron-level marking thiab 3D printing, thiab lwm yam. Ib lub laser nrog M² yam ze li qhov ua tau rau 1 (xws li <1.1) yuav tsum raug xaiv. Lub zog tso zis yuav tsum tau txiav txim siab raws li cov khoom thickness thiab kev ceev ceev. Feem ntau, lub zog ntawm kaum mus rau pua pua watts tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm feem ntau micro-processing. Nyob rau hauv cov nqe lus ntawm wavelength, 1064nm yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv hlau feem ntau vim nws qhov nqus tau siab thiab tus nqi qis ib watt ntawm lub zog laser.
Kev tshawb fawb tshawb fawb thiab kev ntsuas siab kawg: Daim ntawv thov scenarios muaj xws li optical tweezers, txias atom physics, high-resolution spectroscopy thiab interferometry. Cov teb no feem ntau muaj kev mob siab rau ntawm monochromaticity, zaus stability thiab suab nrov ntawm lasers. Cov qauv nrog cov kab dav dav (txawm tias ib zaus) thiab lub suab nrov qis yuav tsum tau muab qhov tseem ceeb. Lub wavelength yuav tsum tau xaiv raws li cov resonance kab ntawm ib tug tshwj xeeb atom los yog molecule (piv txwv li, 780nm feem ntau yog siv rau txias rubidium atoms). Kev saib xyuas tsis zoo yog feem ntau tsim nyog rau kev cuam tshuam kev sim. Lub zog xav tau feem ntau tsis siab, thiab ntau pua milliwatts rau ob peb watts feem ntau txaus.
Kev kho mob thiab biotechnology: Cov ntawv thov suav nrog kev phais mob ophthalmic, kho tawv nqaij thiab fluorescence microscopy imaging. Qhov muag kev nyab xeeb yog thawj qhov kev xav, yog li lasers nrog wavelengths ntawm 1550nm lossis 2μm, uas yog nyob rau hauv lub qhov muag kev nyab xeeb band, feem ntau xaiv. Rau kev kuaj mob daim ntawv thov, kev saib xyuas yuav tsum tau them rau lub zog ruaj khov; Rau kev siv kho mob, lub zog tsim nyog yuav tsum raug xaiv raws li qhov tob ntawm kev kho mob thiab kev xav tau ntawm lub zog. Qhov yooj yim ntawm kev sib kis ntawm optical yog qhov zoo dua hauv cov ntawv thov.
Kev sib txuas lus thiab kev paub: Fiber optic sensing, liDAR thiab qhov chaw kho qhov muag kev sib txuas lus yog cov kev siv. Cov xwm txheej no xav taulaserkom muaj kev ntseeg siab, ib puag ncig adaptability thiab ruaj khov mus ntev. 1550nm band tau dhau los ua qhov kev xaiv zoo tshaj plaws vim nws qhov qis tshaj qhov tsis sib xws hauv cov fibers optical. Rau coherent detection systems (xws li coherent lidar), ib tug linearly polarized laser nrog ib tug heev nqaim linewidth yuav tsum tau raws li ib tug zos oscillator.
2. Kev txheeb xyuas qhov tseem ceeb ntawm qhov tseem ceeb
Tau ntsib nrog ntau qhov tsis sib xws, kev txiav txim siab tuaj yeem ua raws li qhov tseem ceeb hauv qab no:
Txiav txim siab tsis: Ua ntej, txiav txim siab lub wavelength thiab beam zoo. Lub wavelength yog txiav txim los ntawm cov kev cai tseem ceeb ntawm daim ntawv thov (cov yam ntxwv ntawm kev nqus cov khoom, cov qauv kev nyab xeeb, atomic resonance kab), thiab feem ntau tsis muaj chaw rau kev cuam tshuam. Lub beam zoo ncaj qha txiav txim siab qhov ua tau yooj yim ntawm daim ntawv thov. Piv txwv li, precision machining tsis tuaj yeem txais lasers nrog qhov siab tshaj M².
Kev ua tau zoo tsis: Thib ob, them sai sai rau qhov tso zis hluav taws xob thiab kab dav / polarization. Lub hwj chim yuav tsum ua tau raws li lub zog pib lossis kev ua haujlwm ntawm daim ntawv thov. Cov yam ntxwv linewidth thiab polarization yog txiav txim siab raws li cov kev qhia tshwj xeeb ntawm daim ntawv thov (xws li kev cuam tshuam lossis kev cuam tshuam ntau zaus ob npaug). Tswv yim tsis: Thaum kawg, xav txog kev ruaj ntseg (xws li lub sij hawm ntev tso zis fais fab kev ruaj ntseg), kev cia siab (lub sij hawm ua hauj lwm tsis txhaum), ntim hwj chim noj, interface compatibility thiab nqi. Cov kev txwv no cuam tshuam rau kev sib koom ua ke nyuaj thiab tag nrho cov nqi ntawm cov tswv cuab ntawm lub laser hauv qhov chaw ua haujlwm tiag tiag.

3. Kev xaiv thiab kev txiav txim siab ntawm ib hom thiab ntau hom
Txawm hais tias tsab xov xwm no tsom mus rau ib homfiber ntau lasers, Nws yog ib qho tseem ceeb kom nkag siab meej txog qhov tsim nyog ntawm kev xaiv ib hom hauv kev xaiv tiag tiag. Thaum cov ntsiab lus tseem ceeb ntawm daim ntawv thov yog qhov ua tiav siab tshaj plaws, qhov tsawg tshaj plaws tshav kub-tshem tawm tsam, qhov kawg tsom lub peev xwm los yog qhov ntev tshaj plaws kis tau tus mob, ib hom fiber ntau laser yog tib txoj kev xaiv. Hloov pauv, yog tias daim ntawv thov feem ntau cuam tshuam nrog cov phaj tuab, kev kho qhov loj hauv cheeb tsam lossis kev sib kis ntawm lub zog luv luv, thiab qhov tseeb qhov yuav tsum tau tsis siab, ces multimode fiber ntau lasers yuav dhau los ua kev xaiv zoo dua thiab siv tau vim lawv lub zog siab dua thiab qis dua.
