Niaj Hnub Qub Bar Diode Laser Twj Siab Lub Teeb Hwj Kho Siab Diode lossis Diode, Multimode Tib Qws, feem ntau yog los ntawm kev tuav ib qho khoom ntawm ib qho tseem ceeb. Qhov no feem ntau yog 5 mus rau 12 ib-tus qauv hom taub diameterM. Double-clad fiber yog doped nrog lub ntiaj teb tsis tshua muaj ions xws li neodymium, erbium, ytterbium thiab thulium los ntawm ib leeg-hom tub ntxhais. Cov cladding yog ua ntawm doped iav uas muaj qhov ntsuas qis tsis zoo. Lub twj tso kua mis lub teeb yog txhaj rau hauv qhov chaw tuav thiab raws tus qauv, dhau ntawm tus ntxhais nquag thiab ua cov lej ntawm qhov tsis sib xws.
Lub emission wavelength yog xaiv nyob rau hauv lub fiber ntau thiab txhua yam ntawm thiaj muaj nuj nqi (ib tug raug piv txwv yog Bragg gratings).
Lub laser muaj ob qho sib xyaw ntawm ob-lub ntsej muag fiber ntau, ob daim iav thiab qhov chaw tso dej. Cov twj tso kua mis qhov twg los yuav ua tau ib zaug xwb lub teeb-emitting diode, ib tug diode bar los yog ib tug pumped Tib Bar Diode Laser
Cov kev teeb tsa suav nrog ib-hom nruam Ib Leeg Bar Diode Lasers uas tuaj yeem hloov kho kom dhau 100 kHz; Raman zaus hloov ua haujlwm; Q; khoo thiab triple; thiab quasi-nruam yoj (QCW). Cov zis suav nrog UV, pom thiab ze rau duab nrog infrared spectroscopy.
Lub Q-hloov ib leeg Bar Diode Lasers feem ntau yog ua los ntawm lub zog qis, nrog rau kev sib xyaw ib qho pigtail los ntawm cov hluav taws xob fiber ntau rau nanosecond pulsed laser noob. Cov khoom siv fiber ntau, xws li Tib Bar Diode Lasers, raug tsim siv siv cov txheej txheem zoo ib yam; txawm li cas los xij, lub laser tsis muaj qhov kawg kev ntxias cov teebmeem laser. Cov lasers no yog tag nrho monolithic muaj peev xwm ua kom muaj nanosecond pulses los ntawm 20 txog> 200 kHz.
Raman Tib Bar Diode Laser los ntawm ib hom Tib Bar Diode Laser splicing mus rau lub kauj ib leeg-hom tshwj xeeb fiber muaj grating, ntxias Raman zaus hloov mus rau qhov kev kawm wavelength
Pumped Tib Bar Diode Lasers
Diode tuav yuav siv tau los ua kom muaj siab Tib Bar Diode Lasers. Feem ntau, fiber kawg-pumped thiab tsim nyog tej optics siv centralized twj tso kua mis teeb raws li cov thawj pob rau active fiber. Sij hawm dhau los, lub zog hluav taws xob diode muaj qhov tsawg kawg ntawm kev siv hluav taws xob tag nrho, txhim kho lub nqaj thiab lub neej ntev txog 10,000 teev lossis ntau dua, txawm hais tias yuav tsum txias, cov mem tes tuav cov kev txwv thiab kev ntseeg tau raug txwv.
Qhov zoo ntawm lub raj xa dej diodes. Lub ntsiab kom zoo dua yog hais tias lawv tsis yuav tsum tau dej kom txias, muaj peev xwm yuav nkag tau rau hauv lub active nruab nrab los ntawm cov fiber ntawm heev high efficiency, tsis muaj ntxiv tej optics los yog yuav tsum tau muab kho. Tsis tas li ntawd, ib lub teeb xa hluav taws xob tuaj yeem ua rau muaj zog ntau dua cov hluav taws xob thiab cov yam ntxwv zoo dua cov nqaj thiab ntau dua 200,000 teev ntawm kev ua haujlwm lub neej nyob rau hauv kev nruam nruam thiab cov kev hloov kho.
Tib - hom Tib Bar Diode Lasers
Ib Leeg-Ib Leeg Ib Leeg Di Di Lasers muaj nyob rau hauv cov lag luam kev lag luam tau los ntawm ob peb watt txog 3000 watts ntawm cov zis. Tsis tas li ntawd, tib hom kab Ib Leeg Di Di Lasers tau tsim 20 kilowatts ntawm cov haujlwm tshwj xeeb uas siv cov thev naus laus zis kim dua technology. Cov pab kiag li lawm yog feem ntau tas mus li nyob rau hauv lub lag luam; txawm li cas los xij, chav tsev tuaj yeem hloov kho mus rau ntau dua 50 kHz. Hauv cov tes taws los piav cov hom, chav tsev muaj qhov nruab nrab ntawm lub zog nruab nrab. Los ntawm lub M ib leeg-hom fiber nrog ob tug tsawg tshaj li 1.1. Lub laser transverse hom yog purely Gaussian faib.
Piv txwv li, 25 hli collimator collimates nqaj, ua rau muaj 5 hli 1 / E ob puv ntawm 0.3mrad divergence. Nrog ytterbium-doped Ib Leeg Bar Diode Laser, thaum lub lens kawg tau ntxiv, cov txiaj ntsig tau sib npaug ntawm qhov kawg focal ntev muab faib los ntawm focal ntev ntawm lub collimator 7 npaug ntawm cov taub fiber. Nrog kev ua kom tiav thaum kawg ntawm 100 mm thiab 25 mm collimator lens, qhov chaw loj yuav thaum kawg yog 28 [mu] M.
Raws li cov ntaub ntawv teeb tsa yog lub luag haujlwm ntawm tib hom fiber ntau, ntau dua li cov kub ua haujlwm, xws li cov tsoos tau-lub xeev lasers, Ib Leeg Bar Diode Lasers tsim tib lub nqaj hla ntu thoob cov ua haujlwm. Qhov kev hloov kho ua tau los ntawm kev sib hloov ntawm lub twj tso kua mis diode thiab ua tiav, tso cai rau cov cuab yeej ua haujlwm tau hloov kho ntawm qhov muaj qhov siab lossis ib qho kev lag luam mem tes. Nrog cov tsoos tau-lub xeev lasers rau Ib Bar Diode Lasers, nrog nws qhov hla zoo kawg nkaus, tsis muaj lub sijhawm sov so yuav tsum tau thiab tuaj yeem ua haujlwm ntau ntawm ib puag ncig ruaj khov puag ncig (lub zog thiab nqaj zoo). Cov lasers tuaj yeem cuam tshuam nrog cov tso zis tawm ncaj qha, thiab feem ntau muaj peev xwm sib txawv ntawm 10 txog 100 feem pua ntawm lub zog ntsuas tsis muaj qhov sib txawv lossis qhov hloov pauv ntawm qhov kawg tsom teeb pom lub taub.
Kilowatt thiab saum toj no nkaus xwb Bar Diode Lasers nyob rau hauv thaum uas tig mus nrog lub community launch ntawm lub loj inch fiber optic ib leeg-hom Tib Bar Diode Laser raug. Txij ntawm no, lub laser tsis yog ib qho pwm ntxiv mus; txawm li cas los xij, qhov tau txais txiaj ntsig zoo tshaj yog qhov yuav luag txhua qhov lag luam kev lag luam kilowatt-chav lasers (Daim Duab 3). Piv txwv li, 8-kilowatt Tib Bar Diode Lasers muab cov khoom sib txig tsawg dua 4.5 hli x radian los ntawm 100 μm-core-diameter kauj ruam fiber. Qhov kev tsis sib haum xeeb ntawm kilowatt-chav kawm Ib Bar Diode Lasers yuav txuas ntxiv mus ntxiv qhov txiaj ntsig ntawm qhov muaj txiaj ntsig ntawm qhov muaj zog ib leeg-hom module tau siv. Hauv qhov chaw ze, qhov nqaj profile muaj qhov ncaj ncaj ntawm Gaussian, muab qhov zoo tseem ceeb hauv kev siv cov ntaub ntawv thov cov khoom lag luam
Qhov tseeb hom ntawm Ib Leeg Di Di Laser yog quasi-txuas ntxiv. Cov pab kiag li lawm muaj siab ncov lub hwj chim thiab qis nruab nrab lub hwj chim, thiab yuav manufactured nyob rau hauv ib tug ncaj uas tsis muaj nqi tshaj lub CW version. Piv txwv li, 20 kW ncov hluav taws xob thiab lub zog nruab nrab ntawm 2 kW quasi-nruam laser yog li tsib zaug uas pheej yig dua li 20 kW CW laser. Lawv yog cov zoo tagnrho rau ntau daim ntawv thov kev lag luam uas xav tau lub sijhawm ntev ntawm cov mem tes thiab qhov siab tshaj plaws lub zog, xws li chaw vuam, vuam vuam thiab drilling. Tsim los hloov cov tshuab txiav YAG uas twb muaj lawm vim lawv kev tu me thiab tsis tshua muaj nqi quasi-nruam lasers, tuaj yeem kho tau yooj yim rau cov kab ke uas twb muaj lawm. Ib qho qauv thiab ntau hom kev coj ua yog muaj.
