Ua ntej, siv kev tsis ncaj ncees rau qhov cim tau ntawm ntau cov ntsiab lus
Txhua daim iav tsom iav muaj qhov sib txuam ntawm qhov ua kom pom tseeb, thiab cov txheej txheem ntawm deviating los ntawm kev ua kom pom tseeb yuav yooj yim ua rau ntau qhov qauv cim, qhov ntug yog qhov tseem ceeb ntawm qhov tob focal lossis tshaj qhov tob ntawm kev tsom xam, uas yog ntau dua yuav ua rau tsis muaj qhov cuam tshuam. Poj niam txiv neej. Kev tiv thaiv kev zam: Thaum siv txoj kev tiv thaiv kev kos cim, qhov teeb meem ntawm lub zog laser yuav tsum txiav txim siab. Thaum ua haujlwm, qhov cim ntaus cim yuav tsum tsis txhob nyob ntawm lossis dhau ntawm qhov tseem ceeb ntawm cov kab ke focal tob.
Thib ob, lub teeb liab laser tso zis qhov chaw thaiv lossis lub galvanometer deflecting lens puas ntsoog.
Yog tias lub teeb tsa laser tawm lub taub hau, kho kom ruaj khov thiab galvanometer tsis hloov kho ua ntej, qee qhov ntawm cov nqaij ntawd yuav raug thaiv thaum lub laser dhau ntawm lub vibrating lub teeb. Lub chaw ntawm lub teeb txav uas tsom mus rau qhov khoo qhov loj los ntawm lub tshav pob yog qhov tsis ncig. , yuav ua rau cov nyhuv cim tsis zoo.
Yog tias lub galvanometer deflecting lens ua puas, lub laser beam yuav tsis muaj kev cuam tshuam zoo thaum lub laser nqaj hla dhau qhov chaw raug mob ntawm lub lens. Yog li no, lub laser teeb tau tsis sib thooj nrog lub laser lub zog hauv thaj tsam ntawm qhov chaw ntawm lub lens thiab thaj chaw tsis raug mob ntawm lub lens, thiab lub zog laser siv rau cov khoom siv kuj sib txawv, yog li ua cov cim tsis sib xws.
Txav deb ntawm txoj kev: Kho cov teeb liab tso zis tawm lub taub hau, kho kho kom haum thiab galvanometer ua ntej; tiv thaiv galvanometer lens, yog tias muaj kev puas tsuaj, hu rau cov neeg coj ua haujlwm rau kev hloov.
Thib peb, lub thermal teeb meem tshwm sim
Thaum lub laser tau rov nthuav dav lossis rov qab los ntawm qhov muag kho qhov muag, lub lens yog rhuab los tsim cov qhov cuam tshuam me me. Qhov kev rhuav tshem no ua rau lub laser tsom kom sawv thiab focal ntev los ua luv dua. Yog hais tias lub tshuab tsau thiab qhov deb tau kho rau qhov ua kom pom tseeb, lub zog laser ceev ua rau cov khoom hloov vim lub thermal lens tshwm sim tom qab qee lub sijhawm. Nws thiaj li cov cim nyhuv tsis sib xws. Txav deb ntawm cov hau kev: Ua zoo saib rau kev siv txhua hnub. Thaum lub teeb ntuag hloov pauv, tsis hais qhov me me yuam kev, nws yuav tsum tau hloov.
Qeb plaub, lub laser oscillator lens lossis lub teeb ntawm qhov chaw tsis yog cov kab hluav taws xob sib luag nrog lub rooj ua zauv
Yog tias ob qho tsis yog kab rov tav, qhov kev ncua deb ntawm cov kab teeb ci thiab cov khoom tiav yuav tsis zoo ib yam. Lub zog ntawm lub laser poob rau ntawm qhov txheej txheem ua tiav yuav muaj qhov tsis sib xws ntawm lub zog ceev. Kev ua tau zoo ntawm cov khoom siv tsis yog ua cim kev cuam tshuam. Tusyees. Yuav ua li cas kom tsis txhob: Kho qhov theem ntawm lub tshuab ua ntej thiab ua rau lub ntsej muag laser lossis thaj chaw cov kab sib tw rau lub rooj ua haujlwm.
Thib tsib, cov ntaub ntawv vim li cas
Cov khoom siv yog nkag siab nrog lub zog laser teb. Feem ntau, nyob rau hauv tib cov khoom, lub zog laser nce mus txog cov khoom puas pib ua haujlwm yog qee yam. Txawm li cas los xij, yog tias cov tuab ntawm cov khoom txheej yog qhov sib txawv, lossis muaj qee cov txheej txheem kev kho lub cev thiab tshuaj uas tsis sib xws los ua kom lub cev lossis tshuaj pauv rau saum npoo ntawm cov khoom, nws tseem yuav ua rau tsis muaj qhov cuam tshuam tom qab laser npav. Kev zam txoj kev: cov khoom xaiv xaiv ua qhov ceev faj, lub txheej txheej saum npoo yog zoo ib yam, thiab saum npoo kev kho kho lub cev yog ib yam.
Fiber laser npav tshuab muaj ntau cov ntawv thov, tab sis siv sijhawm ntev, vim tias kev saib xyuas tsis nyob hauv qhov chaw, nws muaj peev xwm cuam tshuam rau qhov cim tau, yog li nws tseem ceeb heev uas yuav tsum them sai sai rau kev saib xyuas thiab siv kom raug. Cov.
