Fiber lasers account rau ib qho kev sib koom ntawm kev lag luam lasers txhua xyoo vim lawv cov qauv yooj yim, tus nqi qis, siab electro-optical conversion efficiency, thiab cov txiaj ntsig zoo. Raws li kev txheeb cais, fiber ntau lasers suav txog 52.7% ntawm kev lag luam laser hauv xyoo 2020.
Raws li cov yam ntxwv ntawm cov teeb pom kev zoo, fiber ntau lasers tuaj yeem muab faib ua ob pawg:tsis tu ncua laserthiabmem tes laser. 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 yooj yim ntawm cov ntawv thov hauv cov xwm txheej dav dav.
Raws li lub npe qhia, lub laser tso zis los ntawm ib tug nruam fiber ntau laser yog tas mus li, thiab lub hwj chim yog tswj nyob rau hauv ib tug taag theem. Lub zog no yog lub zog ntsuas ntawm lub laser.Qhov kom zoo dua ntawm cov fiber ntau txuas ntxiv yog lub sijhawm ua haujlwm ruaj khov.
Lub laser ntawm mem tes laser yog "intermittent". Tau kawg, lub sijhawm sib cuam tshuam no feem ntau luv luv, feem ntau ntsuas hauv milliseconds, microseconds, lossis txawm nanoseconds thiab picoseconds. Piv nrog rau cov laser txuas ntxiv, qhov kev siv ntawm cov mem tes laser hloov tas li, yog li muaj cov ntsiab lus ntawm "crest" thiab "trough".
Los ntawm kev hloov pauv mem tes, lub laser pulsed tuaj yeem tso tawm sai sai thiab ncav cuag lub zog siab tshaj plaws ntawm qhov chaw siab tshaj plaws, tab sis vim yog qhov muaj nyob ntawm lub trough, qhov nruab nrab lub zog yog qhov tsawg.Nws yog conceivable tias yog hais tias lub zog nruab nrab yog tib yam, lub hwj chim ncov ntawm lub mem tes laser yuav ua tau ntau npaum li cas ntawm lub nruam laser, ua tiav ib tug ntau zog zog ceev tshaj lub nruam laser, uas yog reflected nyob rau hauv ntau dua kev nkag mus rau hauv lub peev xwm ntawm lub laser. hlau ua. Nyob rau tib lub sijhawm, nws kuj tsim nyog rau cov ntaub ntawv kub-rhiab heev uas tsis tuaj yeem tiv taus kub kub, 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.
CW fiber ntau lasers feem ntau haum rau:
1. Cov khoom siv loj ua haujlwm, xws li tsheb thiab nkoj tshuab, txiav thiab ua cov hlau loj loj, thiab lwm yam kev ua haujlwm uas tsis muaj kev cuam tshuam rau cov teebmeem thermal tab sis muaj kev nkag siab ntau dua rau cov nqi.
2. Siv rau hauv kev phais txiav thiab coagulation hauv kev kho mob, xws li hemostasis tom qab phais, thiab lwm yam.
3. Dav siv nyob rau hauv optical fiber kev sib txuas lus systems rau lub teeb liab kis tau tus mob thiab amplification, nrog siab stability thiab tsawg theem suab nrov
4. Siv nyob rau hauv daim ntaub ntawv xws li spectral tsom xam, atomic physics thwmsim thiab lidar nyob rau hauv lub teb ntawm scientific kev tshawb fawb, muab siab zog thiab siab beam zoo laser tso zis
Pulsed fiber ntau lasers feem ntau haum rau:
1. Precision ua cov ntaub ntawv uas tsis tuaj yeem tiv taus cov thermal los yog cov ntaub ntawv nkig, xws li kev ua cov khoom siv hluav taws xob, cov iav ceramic, thiab cov khoom siv tshuaj lom neeg.
2. Cov khoom siv muaj kev cuam tshuam siab thiab tuaj yeem ua rau lub taub hau laser nws tus kheej tau yooj yim vim kev xav. Piv txwv li, ua cov khoom siv tooj liab thiab txhuas
3. Kev kho deg lossis ntxuav ntawm sab nrauv ntawm cov substrates yooj yim puas
4. Cov xwm txheej ua haujlwm uas yuav tsum tau muaj lub zog siab luv luv thiab qhov tob tob, xws li cov phaj tuab, cov khoom siv hlau drilling, thiab lwm yam.
5. Cov xwm txheej uas cov pulses yuav tsum tau siv los ua cov yam ntxwv ntawm lub teeb liab. Xws li optical fiber kev sib txuas lus thiab optical fiber sensors, thiab lwm yam.
6. Siv nyob rau hauv biomedical teb rau kev phais qhov muag, kev kho mob ntawm daim tawv nqaij thiab cov ntaub so ntswg txiav, thiab lwm yam., nrog siab beam zoo thiab modulation kev ua tau zoo
7. Nyob rau hauv 3D luam ntawv, hlau qhov chaw tsim nrog ntau dua precision thiab complex qauv yuav ua tau tiav
8. Advanced laser riam phom, thiab lwm yam.
Muaj qee qhov sib txawv ntawm pulsed fiber ntau lasers thiab txuas txuas fiber ntau lasers raws li cov hauv paus ntsiab lus, 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 zog siab tshaj plaws thiab kev ua haujlwm ntawm kev ua haujlwm, xws li cov ntaub ntawv ua thiab bio-tshuaj, thaum txuas fiber ntau lasers yog tsim rau cov ntawv thov 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 fiber ntau laser hom raws li cov kev xav tau tshwj xeeb yuav pab txhim kho kev ua haujlwm zoo thiab daim ntawv thov zoo.
