Cov hluav taws xob thiab hluav taws xob zoo ntawm cov laser vuam tshuab tuaj yeem paub tseeb thaum lub sijhawm luam ntawv. Cov neeg muas zaub tuaj yeem piav qhia qhov vuam nyhuv thaum txhim kho cov khoom tshiab thaum pib. Yog li ntawd, nws tsis yog dav dav ntawm no. Txawm li cas los xij, qhov tseem ceeb tshaj plaws yog los qhia cov ncauj lus kom ntxaws txog cov kev hloov kho laser uas cuam tshuam rau kev ncaj ncees ntawm laser vuam.
Tam sim no, laser vuam tshuab muag hauv kev ua lag luam tuaj yeem muab faib ua ob pawg: cov lus tawm tswv yim tam sim no thiab cov zis hluav taws xob tawm tswv yim.
Cov kev tawm tswv yim tam sim no yog cov txheej txheem tswj los tswj lub tam sim no ntawm xenon teeb lub teeb pom kev los ntawm laser los ua kom nws nyob rau txhua lub sijhawm. Txawm li cas los xij, lub zog tsim tawm ntawm lub teeb laser tsis yog linearly proportional rau tam sim ntawd tam sim no ntawm lub xenon teeb nrawm, thiab nrog qhov nce ntawm kev siv lub sijhawm ntawm xenon teeb, cov hluav taws xob hloov pauv hluav taws xob ua kom zoo dua yog qhov txo qis, uas yuav txo lub zog ntawm qhov hloov pauv laser, thiab tom qab ntawd cuam tshuam qhov ncaj ncees ntawm vuam nyhuv.
Laser tawm tswv yim fais fab tawm tswv yim yog kev tswj cov txheej txheem los kho lub twj tso kua mis tam sim no ntawm xenon teeb los ntawm kev ntxiv photodetector ntawm cov zis kawg ntawm cov kab noj hniav laser thiab sib piv cov zis hluav taws xob nrog lub laser nrog cov zis zog ntawm qhov yuav tsum tau laser.
Laser tawm hluav taws xob tawm tswv yim tuaj yeem muab faib rau cov lus qhia tam sim thiab tsis rov qab tawm tswv yim. Cov tswv yim ntawm lub sijhawm tiag tiag yog qhov kev tswj hwm los tswj lub twj tso kua mis tam sim no ntawm xenon lub teeb los ntawm kev sib piv cov ntsuas pom lub zog hluav taws xob nrog lub zog xav tau hluav taws xob tsis pub dhau ib qho mem tes ntawm laser tso zis hluav taws xob. Cov kev tawm tswv yim tsis yog tam sim no yog los sib piv cov zis hluav taws xob waveform ntawm lub dhau los ib tus mem tes nrog lub teeb tsa waveform, thiab tom qab ntawd txiav txim siab txoj kev tswj hwm ntawm qib tam sim no ntawm xenon teeb lub twj tso tawm los tom ntej mem tes laser.
Piv nrog cov kev tawm tswv yim tam sim no, kev tswj qhov tseeb ntawm laser lub zog tso tawm hluav taws xob tuaj yeem txhim kho ntxiv los ntawm kev siv laser tso zis hluav taws xob tawm tswv yim, tshwj xeeb tshaj yog nyob rau hauv cov khoom siv ntau lawm. Tsis tas li ntawd, lub laser vuam tshuab tswj los ntawm laser tso zis hluav taws xob tawm tswv yim yog qhov yooj yim kom paub cov yoj duab hloov kho ntawm lub zog laser. Qhov tseeb, xaiv qhov txawv laser tso tawm lub zog waveforms rau cov khoom sib txawv kuj tuaj yeem ua qhov tseeb vuam nyhuv ua kom zoo dua. Qee zaum, raws li rau cov ntaub ntawv uas tsis tuaj yeem siv los ntawm hom txheej txheem qub, lub teeb hluav taws xob laser tawm tuaj yeem hloov tau Cov kev ua haujlwm vuam zoo tau txais.
Feem ntau hais lus, qhov dav dua txoj haujlwm ua haujlwm yog, qhov loj dua qhov chaw weld yog; lub siab dua cov ntsiab hluav taws xob tso zis hluav taws xob laser tso tawm lub zog yog, qhov kev sib nqus qhov taub loj dua. Nyob rau theem no, tsis muaj kev teeb tsa tiav ntawm laser tso zis hluav taws xob waveform chaw hom, cov neeg tuaj yeem tuaj yeem maj mam tshawb hauv cov ntawv thov txheej txheem, tshawb cov laser tso zis hluav taws xob waveform haum rau lawv tus kheej cov khoom lag luam.
Kev xaiv ntawm laser vuam tshuab yog tshwj xeeb yog qhov tseem ceeb rau cov zis ntsuas ntawm qhov ntau lawm; yog li ntawd, cov neeg siv khoom tuaj yeem xaiv lub laser output fais fab tawm tswv yim vuam tshuab kom sai li sai tau los txhim kho cov khoom lag luam ua kom tiav raws li cov xwm txheej tau tso cai.
