Ntsia Ntsej Muag Diode Laser Yog tias muaj qhov pom tseeb hauv kev lag luam ntawm cov thev naus laus zis thev naus laus zis, uas yog qhov nce ntawm fiber ntau lasers. Hauv kev siv hluav taws xob ntau thiab vuam siv, fiber ntau cov lasers tau los ntawm lub zog hluav taws xob CO2 lasers thiab cov cuab yeej muaj zog-lub xeev lasers kom txeeb tau ntau ntawm cov lag luam sib faib. Tam sim no, ib txhia mainstream fiber laser manufacturers yog kawm ntau yam tshiab daim ntaub ntawv kom tau raws li ntau kev ua lag luam coob.
Hauv cov tshuab hluav taws xob muaj fiber ntau, cov tshuab kaw lus ib hom muaj cov yam ntxwv zoo txaus: lawv muaj qhov ci siab, tuaj yeem tsom mus rau ob peb lub microns rau qhov siab tshaj plaws. Lawv kuj muaj qhov tob tshaj plaws ntawm kev ua kom pom tseeb, Vertical Stack Diode Laser uas ua rau lawv zoo tagnrho rau tej thaj chaw deb machining.
Yuav ua li cas yog cov kev sib tw ntawm tib-hom high-power fiber lasers? Cov kev sib tw yuav tau muab faib mus rau hauv peb lub ntsiab qhov chaw: ib tug) paub siv, b) vim active fibers nrog tsawg kho qhov muag losses thiab kev khiav hauj lwm tsuas nyob rau hauv ib-hom lag luam, thiab c) yog ntsuas ntawm lub resulting tawg. Nyob rau hauv daim ntawv no, peb xav tias kev sib tw ib tug) muaj peev xwm yuav daws tau los ntawm high-brightness laser diodes thiab tsim nyog coupling hom kev kawm, Vertical Tshooj Diode Laser li peb siab nyob rau lwm yam ob kev sib tw chaw.
Nyob rau hauv lub active fiber tsim rau muaj hwj huam ib hom lag luam, Vertical Tshooj Diode Laser muaj ob general tsis optimize: doping thiab geometry. Txhua qhov tsis xws luag yuav tsum raug txiav txim siab kom ua tiav qhov poob qis, ib hom kev ua haujlwm, thiab zaum kawg ua kom muaj zog. Lub tshuab fiber ntau ua kom zoo tshaj yuav muab ntau dua 90% ntawm qhov hloov dua siab tshiab, qhov nqaj zoo tshaj plaws, thiab cov khoom tsim hluav taws xob muaj zog tsuas yog los ntawm cov tswj lub zog muaj.
Txawm li cas los, lifting ib zaug xwb hom system mus rau ib tug ntau dua hwj chim tej zaum yuav raug nyob rau hauv ib tug ntau dua hwj chim ceev tsis pub dhau lub active tub ntxhais, ib tug muaj zog thermal load, thiab ntau non-linear kho qhov muag los xws li tsa Raman scattering (SRS) thiab tsa Brillouin scattering (SBS) Cov.
Cov feem ntau cov tawm yog cov raug cov nyhuv ntawm lub ytterbium-doped quartz fiber, thiab nws yog zoo dua lub npe hu nyob rau hauv lub hnub thaum ntxov thaum fiber lasers yog tsis ntshiab li niaj hnub no, thiab qhov no yog phototaxis. Nyob rau hauv txoj kev no, Ntsug Stack Diode Laser vim qhov sib cuam tshuam ntawm cov khoom siv laser, qhov chaw tsis xws luag lossis lub chaw ua xim yog tsim hauv cov khoom siv. Cov nyhuv no yog cov kab mob parasitic: nws hloov cov twj tso kua mis photons rau hauv tshav kub, uas ua rau muaj qhov qis dua kom pom tseeb thiab nce cov cua sov kom.
