Laser fiber ntau yog dab tsi?
Lub laser fiber ntau los yog fiber ntau lub laser yog ib lub laser nyob rau hauv qhov nquag nce nruab nrab yog ib qho siv fiber ntau doped nrog tsawg lub ntiaj teb hais xws li erbium, ytterbium, neodymium, dysprosium, praseodymium, thulium thiab holmium. Lawv muaj feem xyuam rau doped fibre amplifiers, uas muaj lub teeb amplification tsis muaj kev nrawm. Fiber nonlinearities, xws li stimulated Raman tawg lossis plaub-nthwv mixing kuj yuav muab qhov nce thiab yog li pab tau txais kev tshaj tawm rau laser fiber ntau.
Zoo
Qhov zoo ntawm cov las las fiber ntau dua lwm yam:
Lub teeb yog twb tau muab tso rau hauv ib lub flexible fibre: Qhov tseeb tias lub teeb yog twb nyob rau hauv ib lub fiber ntau nws yuav muab tau yooj yim tauj mus rau lub tsom ncaj rau lub caij. Qhov no yog qhov tseem ceeb rau cov laser txiav, txuas, thiab folding ntawm co thiab polymers.
Cov zis muaj hwj chim loj: Fiber lasers muaj peev xwm muaj peev xwm thaj chaw ntau lub voj voog ntev ntev, thiab thiaj li muab tau qhov siab tshaj qhov muag tau. Lawv tuaj yeem txhawb kilowatt theem ntawm cov zis txuas zais zis vim yog qhov fiber ntau qhov chaw siab ntim rau ntim piv, uas tso cai rau cov dej txias.
Siab kho qhov muag zoo: Lub fais fab cov khoom siv lub zog ua kom tsawg los yog tshem tawm cov thermal distortion ntawm txoj kev kho qhov muag, feem ntau ua ib qho kev txwv qis qis, siab zoo tshaj plaws.
Kev loj hlob loj: Cov Fiber Lasers yog sib cog ua piv rau cov pas nrig lossis roj nkev ntawm lub zog uas zoo sib xws, vim hais tias cov iav muaj peev xwm khoov tau thiab coiled kom txuag tau qhov chaw.
Kev Ntseeg: Fiber lasers pom siab kub thiab kev vibrational stability, ncua kev siv mus ntev, thiab kev lag luam tsis pub dawb ntawm lub lag luam.
Siab ncov lub zog thiab nanosecond pulses pab tau zoo thiab kos duab.
Lub zog ntxiv thiab zoo dua nqaj zoo dua yuav muab cov chaw ntxhua khaub ncaws txiav tawm thiab ceev ceev ceev.
Txo tus nqi ntawm cov tswv cuab.
Fiber lasers yog tam sim no yog siv los ua kom siab-ntws (SAW) nruab nrab. Cov lasers tau los ntawm kev lag luam thiab txo tus nqi ntawm cov tswv cuab uas zoo dua rau cov laus hauv xeev-state laser tshuab.
Daim ntaub ntawv
Cov kev siv cov las phom muaj xws li cov khoom siv (kos, kos duab, txiav), kev sib txuas lus, spectroscopy, tshuaj, thiab cov khoom siv hluav taws xob muaj zog.
