Laser, ib qho cuab yeej uas txhawb nqa cov atoms lossis cov molecules kom tawm lub teeb ntawm cov wavelengths tshwj xeeb thiab nthuav tawm lub teeb, feem ntau ua rau lub teeb nqaim heev ntawm cov hluav taws xob. … Laser yog ib tug acronym rau "lub teeb amplification los ntawm lub stimulated emission ntawm hluav taws xob. "
Dab tsi yog luv rau Lub Teeb Pom Kev Zoo los ntawm Kev Tshaj Tawm Tshaj Tawm ntawm Radiation?
Lo lus laser yog cov lus luv rau cov lus "lub teeb nthuav dav los ntawm kev txhawb nqa emission ntawm hluav taws xob." Hauv lwm lo lus, lub laser yog ib lub cuab yeej muaj peev xwm hloov lub teeb lossis hluav taws xob hluav taws xob rau hauv lub teeb tsom, lub zog siab.
Dab tsi yog kev siv lub teeb Amplification los ntawm Stimulated Emission of Radiation?
Nyob rau hauv kev kho hniav kho hniav, ntau hom lasers tau tsim rau kuaj mob (xws li kuaj pom caries) thiab kev siv cov ntawv thov (xws li cov hniav ablation, kab noj hniav npaj, kho dua tshiab, bleaching.).
Thaum twg Lub Teeb Amplification los ntawm Stimulated Emission of Radiation?
Xyoo 1905, Einstein tau tso nws daim ntawv ntawm cov nyhuv photoelectric, uas tau hais tias lub teeb tseem xa nws lub zog hauv chunks, qhov no discrete quantum hais tam sim no hu ua photons. Hauv 1917, Einstein tau npaj cov txheej txheem uas ua rau lasers ua tau, hu ua stimulated emission.
Yuav ua li cas emissions tsim lub teeb amplification?
Qhov kev nthuav dav tseem ceeb ntawm kev tawm dag zog yog tias cov photon induced muaj tib zaus thiab theem raws li qhov xwm txheej photon. … Txawm li cas los xij, qee qhov photons ua rau muaj kev tawm dag zog hauv lub xeev cov atoms, tso lwm cov photon coherent. Nyob rau hauv qhov tseeb, qhov no ua rau optical amplification.

Thaum twg yog lub teeb hluav taws xob tsim hluav taws xob?
Lub teeb sodium siab tsawg tau tsim ua ntej hauv 1920 los ntawm Arthur H. Compton ntawm Westinghouse. Thawj lub teeb yog lub teeb puag ncig nrog ob lub electrodes ntawm txhua sab . HPS tau tsim thaum twg? HPS teeb tau tsim thiab qhia hauv 1968 ua qhov chaw siv hluav taws xob zoo rau sab nrauv, kev ruaj ntseg, thiab kev siv teeb pom kev zoo, thiab tshwj xeeb tshaj yog nyob rau hauv kev siv teeb pom kev zoo .
Yuav tsum tau hloov cov hluav taws xob hluav taws xob nrog cov hluav taws xob?
Kuv puas yuav tsum hloov cov hluav taws xob hluav taws xob nrog cov hluav taws xob? Ignition coils thiab spark plugs ua haujlwm zoo ua ke. … Tab sis yog tias koj tsuas yog hloov koj lub qhov hluav taws xob ua ib feem ntawm kev saib xyuas niaj hnub, nws tsis tsim nyog los hloov koj cov hluav taws xob hluav taws xob tib lub sijhawm tshwj tsis yog muaj cov cim qhia tias lawv ua tsis tau Yuav tsum hloov cov hluav taws xob hluav taws xob ntau npaum li cas?
Puas yog roj hluav taws xob hluav taws xob hluav taws xob zoo?
Central gas heating systems siv natural gas rau tsev sov. Kuv xav siv cov pa roj carbon monoxide tsis zoo rau lub hauv nruab nrab cua sov vim tias nws yooj yim, yooj yim, txhim khu kev qha, thiab ua haujlwm zoo dua. Thaum tshav kub kub uas los ntawm cov nkev ntuj pom tau tias sov dua li cua sov tawm ntawm lub hauv paus system .
Lub tshuab hluav taws xob twg yog qhov zoo tshaj plaws rau lub tshuab hluav taws xob?
Lub DC lub cev muaj zog yog qhov zoo tshaj plaws rau lub tshuab hluav taws xob. Nws yuav tsim tam sim no, txawm tias qhov ceev ntawm kev sib hloov yog me ntsis tsawg. Thaum koj siv ib theem lub cev muaj zog, koj yuav tsum tig nws ntawm qhov nrawm dua li cov motors synchronous ceev kom tsim tau lub zog .
Puas nthuav tawm zaub mov rau hluav taws xob ua rau nws muaj hluav taws xob?
Irradiation tsis ua rau cov zaub mov muaj xov tooj cua, cuam tshuam cov khoom noj khoom haus zoo, lossis pom qhov hloov pauv saj, kev ntxhib los mos, lossis cov tsos ntawm cov zaub mov. Qhov tseeb, txhua qhov kev hloov pauv los ntawm irradiation tsawg heev uas nws tsis yooj yim los qhia yog tias cov zaub mov tau irradiated .
