Ntau lub tuam txhab ua lag luam koom nrog laser npav cim kev ua haujlwm yuav nug thaum nriav cov cuab yeej siv: cov tshuab no puas muaj lub teeb liab kho lub teeb? Dab tsi yog lub luag haujlwm ntawm no" kev cai teeb liab liab" ;?
1. Kho cov txheej txheem kho qhov muag ntawm resonator
Txoj haujlwm ua haujlwm ntawm cov resonator yog raws li kev cuam tshuam ntawm ntau nqaj hauv kab noj hniav, thiab ib qho ntawm cov txheej txheem yooj yim rau kev cuam tshuam yog kev sib tsoo ntawm cov kab teeb nyob hauv qhov chaw, uas xav kom peb tswj cov kev taw qhia ntawm cov kab teeb heev kom yog txhawm rau coj lawv mus rau hauv cov resonator, uas yog, kho qhov muag kab noj hniav txuas. Piv txwv, semiconductor laser npav tshuab.
2. Txoj Haujlwm
Tsuas yog thaum txoj haujlwm cim tau hloov kho, tuaj yeem ua cov txheej txheem thiab ntau lawm. Raws li cov software khij khoom sib txawv, nws muaj peev xwm muab faib ua cov cim kev qhia pom tseeb, 9-taw qhia txog ntawm tus cim ntaus cim, qhov ntev thiab qhov dav ntawm qhov ntsuas ntawm tus qauv cim, thiab tag nrho kev sim ua piv txwv ntawm cov qauv cim.
3. Kev tsom xam
Lub teeb liab kuj tseem siv tau los ua qhov tseem ceeb ntawm lub cim laser tshuab, uas yog qhov ntsuas ntawm qhov cim kev nrug (qee lub teeb liab yuav tsis pom, qee zaum lub teeb liab yuav tshwm sim, tab sis tsuas yog lub teeb liab yuav qhib thiab tawm, tab sis tsis muaj lub teeb pom kev tshwm sim). Qhov deb ntawm ob lub teeb liab liab tshwm sim nrog qhov deb ntawm npav cim tshav dav hlau iav. Nyob rau hauv txoj kev no, nws tsis tas yuav siv tus pas ntsuas steel los ntsuas qhov cim kev nrug ntawm txhua lub sijhawm cov khoom raug hloov, uas txo cov qib ua haujlwm thiab txhim kho qhov cim nrawm.
Muaj ib qho yuav tsum tau them nyiaj tshwj xeeb rau: los tig lub teeb liab kom haum ntawm lub npav laser cim xav tau tus neeg teb xov tooj kom muaj kev nkag siab qee yam ntawm cov khoom siv. Piv txwv li, feem ntau, qhov teeb liab liab hloov kho ntawm lub cim software. Nias F1 kom tig nws. Yog tias koj tsuas pom tias lub galvanometer tau txav mus thiab tsis muaj lub teeb liab tawm los, ua ntej xyuas seb lub tshuab hloov ua hluav taws xob kom tswj lub teeb liab tsis nyob. Kuaj seb lub hwj huam hluav taws xob liab nyob rau ntawm no. Siv lub multimeter los ntsuas seb puas muaj 5V voltage ntawm ob lub teeb liab thiab dub ntawm lub teeb taw qhia lub teeb liab, Yog tias qhov hluav taws xob yog 5V thiab tsis muaj qhov tso zis tawm laser, tom qab ntawd lub teeb liab liab yuav tsum tau hloov.
Muaj qee tus laser npav tshuab tsim tshuab, txhawm rau txuag nqi, tsis muaj kev ua haujlwm zoo li no, peb yuav tsum mob siab rau qhov no thaum peb xaiv lub laser npav tshuab. Ib lub tshuab ua cim laser tiav, yuav yeej muaj cov teeb liab qhia teeb liab, koj puas muaj tag nrho koj cov khoom siv?
