Cov kab ke unterminated unterminated fibers, FC / PC txuas, lossis FC / APC txuas

Focc muaj cov lus piav qhia me me ntawm 405 ± 5 nm, nrog kev faib sib piv xaiv tau los ntawm 99: 1. Coupler cov teeb tsa suav nrog 1x2, 2x2, thiab 1X4. Vim yog lub suab luv luv ntawm 405 nm teeb, ob peb yam ntxiv yuav tsum tau txiav txim siab thaum xaiv cov khoom siv uas tsim nyog 405 NM coupler rau ib daim ntawv thov.

Cov kev txiav txim siab tseem ceeb

Fiber Optics: Ob qho qauv sib txawv muaj, ob qho tib si kev sib txuas ib leeg {{}}}}} {{- cov tub ntxhais hais fiber ntau. Lawv cov kev ua haujlwm ua haujlwm hnyav yog 400 nm mus rau ntau dua lossis sib npaug rau 635 nm. Rau ib tug lej aperture (na) ntawm 0.12, lub tub ntxhais txoj kab uas hla ntawm germanium- doped fiber yog 2.1 μm; Thaum tib yam nyob rau tib lub na, cov tub ntxhais txoj kab uas hla ntawm cov ntshiab silica {{}} tub ntxhais fiber yog 3.0 μm.

Core loj:
Lub tub ntxhais lub cheeb tsam uas yuav tsum tau rau 405 nm ib qho {}} hom fiber ntau dua li peb zaug me me (piv txwv li syming smf {{{}} 28). Vim yog cov tseem ceeb me me, cov fibers yuav tsum muaj cov kev ncaj ncees tsis muaj tseeb thaum kev txiav tawm hauv FC / PC lossis FC / APC Fiber Optic Connector Ferrules. Ib qho kev ua txhaum cai ntawm cov tub ntxhais muaj fiber ntau thaum txuas tau mated ua ke (piv txwv li, hauv lub diaphragm) tuaj yeem ua rau muaj kev poob zoo. Tsis tas li ntawd, kev sib sau ua ke ntawm me me- cov tseem ceeb ib-hom fibers yuav tsum tau ua cov txiaj ntsig tshwj xeeb kom ua tiav.

Attenuation rau 405 nm teeb kis

Fiber ntau yog inherly ntau dua li ntawm cov tsoos ib txwm - Infrared / Telecomunications Fibers. Piv txwv li, kev ua kom muaj fiber ntau siv los hloov cov fiber ntau dua lossis sib npaug ntawm 0.15 nm teeb yog feem ntau tsawg dua lossis sib npaug txog 30 dB / KM.

Vim yog cov me me core core ntawm ib qho - hom kev sib zog yog raug rau kev sib zog 405 n- kev puas tsuaj.

Hauv 3 μm ntshiab silica - cov me nyuam sib nraus, lub zog nthwv dej lub teeb yog 70.7 kw / cm ²; Thaum nyob rau hauv 2.1 μm Germanium- doped core core fiber ntau, lub zog ntom ntom rau tib lub zog yog siab npaum li 144.4 kw / cm². Ib qho av, roj, lossis roj rau ntawm cov kab ke fiber ntau, muaj peev xwm ua rau muaj kev sib cav sib ceg lossis kev ua kom zoo dua nyob rau hauv theem kho qhov tsis muaj nqi. Vim tias lawv cov txheej txheem loj dua, ntshiab silica {{} Cov tub ntxhais muaj kev puas tsuaj rau kev puas tsuaj rau germanium {{}} doped fibers. Silica ntshiab silica - Cov tub ntxhais tseem ceeb rau lub zog tawm saum toj 5 txog 10 mW.

Qhov no txhais tau hais tias kev ua kom tsis txhob nqus tau los ntawm kev nqus lossis tawg ua kom nce sijhawm. Lub chaw tsim xim tsim qauv cuam tshuam nrog cov teeb pom kev zoo nrog cov roj ntsha thiab kev ntxhov siab tam sim no tsim tawm thaum muaj kev teeb tsa fiber ntau, tsim cov ntawv me me hauv cov fiber ntau. Nws nyob ntawm cov hom fiber, lub wavelength thiab kev siv ntawm lub teeb, thiab lub sijhawm raug. Cov nyhuv no yog kev coj ua tab sis, qee qhov xwm txheej, reversible. Photodarkening tuaj yeem cuam tshuam qhov kev ua tau zoo ntawm kev ua kom muaj fiber ntau lossis fiber ntau optic ntaus ntawv siv ntawm 405 nooj txawm muab cov fiber ntau. Silica ntshiab silica - cov tub ntxhais ua piv txwv txog lub chaw teeb tsa xim ua piv rau Germanium {}} doped fibers.
