Fiber Coupled Diode Laser siv tsis tshua muaj lub ntiaj teb doped fibers ua lub nruab nrab nquag, nrog laser diodes raws li lub twj tso kua mis, uas inherently muaj qee qhov tseem ceeb, ua rau lawv nyob rau hauv lub pwm los ntawm tiam ntawm luv luv-luv mem tes yog qhov txaus nyiam heev. Qhov siab nce bandwidth thiab ua haujlwm ntawm doped fibers tso cai rau kev tsim cov khoom pheej yig, kev cog lus, rugged fiber ntau lub tshuab laser uas muab cov kab ke uas muaj fiber ntau ua rau ntau cov ntawv thov.
Lub fiber muab ib tug siab deg hauv cheeb tsam-rau-volume ratio, uas enables npaum txias thiab yuav Mekas raws li tej kev kawm tsis. Fiber Coupled Diode Laser yog pib txwv rau kev nruam (CW), qis zog, ib hom haujlwm ua haujlwm. Tom qab ntau tshaj 30 xyoo ntawm txoj kev loj hlob, Fiber Coupled Diode Laser tau ua tiav ib qho thiab multimode kev ua haujlwm, yoj yob sib nrug npog UV (UV) mus deb deb infrared (Far-IR) band, thiab tuaj yeem muab lub zog siab, qib rov ua dua. zaus, thiab (tej zaum tseem ceeb tshaj plaws) milliseconds rau femtosecond mem tes dav.
Tsis zoo li cov lasers dawb-chaw siv, Fiber Coupled Diode Laser siv fiber ntau thiab fiber ntau Bragg gratings (FBG), uas hloov cov iav dielectric pom zoo rau kev siv tswv yim kho qhov muag. Feem ntau cov cuab yeej siv hluav taws xob Fiber Coupled Diode Laser siv ob chav sib xyaw ua ke fiber ntau architecture, qhov twg qhov nce qhov nruab nrab yog nyob rau hauv cov tub ntxhais fiber, puag ncig los ntawm ob txheej txheej cladding. Lub multimode twj tso kua mis nqaj teeb los ntawm ib lub laser diode los yog lwm lub fiber fiber laser kev faib tawm sab hauv sab hauv cladding thiab raug txwv los ntawm sab nraud cladding kom muaj siab rau cov nruab nrab nquag thiab tsim hom kev sib kis uas nthuav tawm hauv cov tub ntxhais fiber.
Txhawm rau tsim cov tshuab nqus laser ntev cov pa taws, nquag lossis nquag hom kev xauv khawm cov cuab yeej yog qhov yuav tsum tau ua. Qee qhov kev qhia niaj hnub no siv rau kev ntsuas lub qhov ntsuas lub ntsej muag suav nrog kev sib hloov tsis sib hloov kev sib txuas thiab lub ntsej muag nqus tau, thaum electro-optic lossis acousto-optic modulators siv rau hom kev ua haujlwm-txhav tas.
Nyob rau hauv semiconductor saturable absorber (SESAM), semiconductor quantum dej yog zus nyob rau hauv semiconductor faib Bragg reflectors, thiab SESAM muaj tau ntse siv mus fabricate femtosecond Fiber Coupled Diode Laser kev khiav hauj lwm ntawm 1.0 μm thiab 1.5 μm wavelengths. Kev siv ntawm erbium-doped (Er) Fiber Coupled Diode Laser siv graphene saturable absorbers tau qhia tus kheej kev pib hom-xauv thiab ruaj khov soliton pulses. Cov no yog cov cia li ib tug ob peb femtosecond fiber laser architectures uas coj mus muag lasers siv kom tau raws li ib tug ntau yam ntawm scientific thiab muaj kev siv.
Fiber Coupled Diode Laser yog ib qho zoo tagnrho xaiv rau kev siv cov R / LM2 txheej txheem vim hais tias lawv muab qhov yuav tsum tau siab tso zis ntau zog (txog 800W) thiab nyob ze infrared (NIR) wavelengths, thiab muab piv rau lwm yam hom lasers xws li flash Pumped pulsed Nd: yag lasers, Fiber Coupled Diode Laser muaj cov nqi khiav lag luam qis dua thiab kev tu xyuas ntev dua.
Hauv tib-kab hluav taws xob laser diode-thawj-tiam fiber ntau laser, ntau ntawm txhua lub twj tso kua mis feem ntau fused ua ke kom ua tiav qhov siab kawg. Txawm hais tias hom no feem ntau muaj zog heev, nws yog qhov tshwj xeeb tshaj tawm rau sab nraub qaum los ntawm cov khoom siv phiaj. Yog li ntawd, hauv kev kho cov ntawv muaj hlau, xws li tooj liab thiab tooj dag, koj yuav tsum siv qee hom kev rho tawm kho qhov muag. Nyob rau hauv tas li ntawd, siv ntawm fused Cheebtsam (tej zaum nrog rau qhov kawg kis tau tus mob fiber) txhais tau hais tias cov lasers yuav kho tsis tau rau ntawm qhov chaw. Yog li, yog tias ib qho kev tivthaiv me ntsis kev puas tsuaj, tag nrho cov laser yuav tsum rov qab mus rau lub Hoobkas rau kev hloov.
Coherent Kev siv txoj hauv kev tshiab los hloov kho rau Fiber Coupled Diode Laser ua raws feem ntau ntawm cov khoom siv hluav taws xob semiconductor lasers, tsis yog ib leeg Emitters, raws li lub twj tso kua mis. Lub teeb tawm los ntawm cov twj tso kua mis tawm kab tawm yog qhia rau hauv qhov nce fiber siv cov nqaj sib txuas ua ke ntawm cov txiav tawm kho qhov muag. Cov nqaj txuas ntxiv kuj ua kom txoj kab teeb tsa ntawm qhov nce cov zis fiber ntau, thiab tom qab ntawd lwm cov ntsiab lus kho qhov muag tau zoo txuas rau qhov kawg thauj fiber ntau.
