- Fiber ntau lasers chaw kua zaub
Laser DiodesRaws li twj tso kua mis:Fiber ntau ua ntej siv laser dodes raws li lawv cov kua mis tau ua rau lawv muaj peev xwm ua tau ib qho kev ua kom haum rau cov khoom nqus ntawm doped fiber ntau. Kev xaiv ntawm laser diode yoj yog qhov tseem ceeb; Piv txwv li, ib qho dopant nyob rau hauv fiber ntau ytterbium (YB), uas muaj qhov zoo dua peak ib ncig ntawm 976 nm. Yog li ntawd, laser dodes emitting emitting nyob rau los yog nyob ze no nthwv dej yog nyiam rau nqus yb-doped fiber ntau lasers.
Muab ob npaug rau-clad fiber tsim:Txhawm rau nce kev ua tau zoo ntawm lub teeb nqus ntawm lub cev laser dieres, cov lasers fiber ntau feem ntau siv ob-clad fiber tsim. Cov tub ntxhais sab hauv yog doped nrog cov nquag uaer nruab nrab (piv txwv li, Cov tub ntxhais muaj lub twj tso kua mis lub teeb ci thiab tsim cov chav tsev laser, thaum lub cladding tso cai rau qhov ntau dua ntawm cov twj tso kua mis kom sib cuam tshuam nrog cov tub ntxhais, txhim kho kev ua tau zoo.
Wavelength matching thiab txuas kev ua tau zoo: Cov twj tso kua mis tsis tas yuav tsum tsis txhob xaiv cov laser dieres nrog cov wavelength kom tsim nyog ntawm kev ua haujlwm ntawm dodes thiab muaj fiber ntau. Qhov no suav nrog ua kom zoo ib yam nkaus thiab kho qhov muag cov ntsiab lus zoo li lo ntsiab muag thiab cov coupkers los xyuas kom meej lub teeb rau cov tub rog fiber ntau lossis cladding.
-Khoom-Lub Xeev LasersTwj Tso Cai
Kho Dua Qhov Muag:Dhau li laser diodes, ruaj khov cov lasers (suav nrog cov lasers loj zoo li ND: Yag) tuaj yeem siv hluav taws xob nrog lub teeb nyem lossis lub teeb lub teeb.
