1651nm 20mW Npauj Npaim Fiber Coupled Diode Laser
Lub 1651nm 20mW Npauj Npaim Fiber Coupled Diode Laser yog muaj nyob rau hauv tus qauv 14-pin npauj npaim pob nrog kev sib xyaw ua ke thermoelectric txias, thermistor thiab photodiode rau kev ua haujlwm ruaj khov. Nws yog ua ke rau ib hom fiber ntau los muab cov khoom tso tawm kom zoo thiab ruaj khov. Txhua tus pin hauv pob npauj npaim muaj qhov tshwj xeeb rau kev tswj xyuas meej. Nrog ib tug linewidth tsawg dua 300kHz, lub laser yog zoo tagnrho rau high-resolution gas sensing daim ntaub ntawv xws li TDLAS thiab CH₄ nrhiav kom tau. Nrog rau lub zog tso zis ntau dua 20mW thiab zoo heev wavelength stability, nws ua kom ntseeg tau kev ua tau zoo nyob rau hauv ib puag ncig hnyav.
Npauj npaim fiber ntau-coupled diode lasers yog nrov vim lawv compact, txhim khu kev qha, thiab yooj yim rau kev khiav lag luam. Lawv cov pob khoom suav nrog ua - hauv kev tswj qhov kub thiab txias (xws li TECs thiab thermistors) thiab photodiodes rau kev saib xyuas, uas pab ua kom lub laser ruaj khov nyob rau lub sijhawm. Cov zis fiber ntau (feem ntau yog tib hom - hom lossis PM) ua rau nws yooj yim heev rau kev txuas mus rau lwm cov khoom siv, thiab cov nqaj zoo yog huv thiab zoo ib yam. Txhua tus pin ntawm pob 14-pin muaj cov haujlwm meej, uas ua rau kev sib koom ua ke yooj yim heev. Hauv cov ntsiab lus, lub laser no yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov xws li kev tshawb nrhiav roj, spectroscopy, thiab chaw kuaj mob, qhov chaw ruaj khov thiab qhov tseeb yog qhov tseem ceeb.

Tib -hom thiab multimode fibers sib txawv feem ntau nyob rau hauv lawv kis lub teeb thiab rau lub hom phiaj dab tsi. Tib - hom fiber ntau muaj lub hauv paus me me uas tso cai rau tib txoj kev rau lub teeb. Qhov no ua rau lub teeb huv si, ruaj khov nrog qhov sib txawv tsawg, zoo tagnrho rau kev ntsuas roj, spectroscopy, lossis ib qho kev teeb tsa uas xav tau qhov tseeb thiab ntev - lub sijhawm ruaj khov.
Hauv qhov sib piv, multimode fiber ntau muaj lub hauv paus loj dua, thiab lub teeb mus los ntawm ntau txoj hauv kev. Qhov no ua rau cov kab teeb tsis sib xws, tab sis nws tuaj yeem siv tau ntau lub zog thiab feem ntau yog siv rau luv luv - nrug lossis siab - siv fais fab - xws li teeb pom kev zoo lossis kev kho mob, qhov tseeb kab teeb tsis tseem ceeb.
Yog li, feem ntau, yog tias koj ntsuas qhov tseeb thiab kab teeb zoo, xaiv ib hom - hom. Yog tias koj xav tau lub zog ntau dua, thiab kab teeb duab tsis yog qhov tseem ceeb, multimode tej zaum yuav zoo dua rau koj.
Cov kab dav ntawm peb cov khoom yog tsawg dua 300kHz. Ib txoj kab dav hauv qab 300kHz txhais tau hais tias lub teeb los ntawm lub laser yog ruaj khov thiab ntshiab, nrog tsawg zaus sib txawv. Nyob rau hauv luv luv, cov xim ntawm lub teeb laser tsis txawv ntau thiab ruaj khov heev. Txoj kab dav dav no yog qhov tseem ceeb rau cov ntawv thov xws li siab - ntsuas qhov tseeb, spectroscopy, thiab kev ntsuas roj, qhov twg lub teeb pom kev huv, ruaj khov tuaj yeem ua rau muaj qhov tseeb thiab ntseeg tau.
Cov khoom no los nrog ib qhoFC/APCtxuas. Qhov sib txawv tseem ceeb ntawmFC/PCthiabFC/APCconnectors nyob rau hauv lub fiber kawg -lub ntsej muag lub kaum sab xis thiab yuav ua li cas lawv txo rov qab reflections. FC/PC connectors muaj lub tiaj los yog polished me ntsis kawg -lub ntsej muag thiab muab kev sib raug zoo, tab sis lawv tuaj yeem ua rau muaj kev xav rov qab siab dua. FC/APC connectors muaj 8-degree angled kawg-lub ntsej muag, uas yuav pab txo qis rov qab xav txog qhov tseem ceeb. Qhov no ua rau FC/APC connectors tsim nyog rau daim ntawv thov uas yuav tsum tau ruaj khov, qis- suab nrov kho qhov muag teeb liab, xws li high-precision sensing thiab kev sib txuas lus systems.
Yog tias koj txaus siab rau cov khoom no, thov koj xav paub ntxiv txog tus nqi thiab specification.
