Taw qhia rau txoj kab kab noj hniav ntsugSemiconductor laser(Vcels)
Ntsug sab nraud kab noj hniav nto-emitting lasers tau tsim nyob rau hauv ib nrab teeb meem uas tau ua rau muaj cov teeb meem tseem ceeb uas tau ua rau muaj kev ua kom muaj zog ntawm Beamente hom.
Ntsug sab sab nruab sab kab noj saum npoo-emitting lasers (vecsels), tseem hu uasemiconductor disc lasers(SDL), yog ib tug tswv cuab tshiab ntawm lub laser tsev neeg. Nws tuaj yeem tsim lub zog emissenh los ntawm kev hloov cov khoom siv sib xyaw ua ke los ntawm Quardegence Nce cov khoom nruab nrab, thiab ua ke nrog cov khoom siv hluav taws xob tsawg kawg nkaus los ntawm cov khoom nruab nrab ntawm cov khoom nruab nrab Lub Laser Revonator yog tsim los ntawm lub hauv qab dbr qauv ntawm qhov nce thiab cov zis sab nraud txuas nrog daim iav. Qhov kev sib txawv ntawm tus qauv resonator sab nraud tso cai rau cov kab noj hniav xws li zaus sib txawv, thiab hom kev xauv, ua rau vecsingLaser Taurau cov ntawv thov xws li bioophotonics, spectroscopy,Laser tshuaj, thiab laser projection.
Tus resonator ntawm VC-nto teeb sementonductor laser yog qhov chaw nyob rau qhov chaw nquag, thiab cov kab noj hniav loj, thiab cov txheej txheem ntau lawm. Nws qhia tau zoo heev hauv cov ntawv thov ntawm laser zaub, kev sib txuas lus kho qhov muag thiab lub moos sib txuas lus kho qhov muag. Txawm li cas los xij, VCSELS tsis tuaj yeem tau txais cov neeg siv lub zog siab dua lub watt theem, yog li lawv tsis tuaj yeem siv rau hauv liaj teb nrog cov kev xav tau siab.

Cov khoom siv laser ntawm vcahs yog tsim los ntawm cov qauv hluav taws xob rov qab los ntawm cov khoom siv sib txawv ntawm cov khoom sib txawv ntawm cov cheeb tsam sab saud thiab sab saud, uas txawv ntawm covlaserResonator muaj kev cuam tshuam ntawm cov dav hlau hauv eel. Cov kev taw qhia ntawm VCEL kho kho qhov muag ua haujlwm yog txiav rau cov nti saum npoo, thiab cov kev cuam tshuam ntawm cov dbr yog siab dua li ntawm cov EEL daws dav hlau.
Qhov ntev ntawm lub laser resonator ntawm vcels feem ntau yog ob peb lub microns, uas yog ntau dua li ntawm cov EV, thiab txoj kev nce los ntawm Optical teb oscillation nyob rau hauv cov kab noj hniav os. Txawm hais tias qhov tseem ceeb hloov cov khoom siv hloov mus tau ua tiav, cov zis hluav taws tuaj yeem tsuas yog mus cuag ob peb milliwatts. Cov ntoo khaub lig-seem ntawm VCSaser Beam yog ncig, thiab lub kaum ntse ntse ntau dua li cov ntug-emitting nqaj. Yuav kom ua tiav lub zog siab tawm ntawm vcels, nws yog ib qho tsim nyog yuav nce cov cheeb tsam luminous kom muab cov teeb tsa ntau dua, thiab nce cov zis ua kom muaj ntau hom zis. Nyob rau tib lub sijhawm, nws yog qhov nyuaj rau kev ua kom tiav cov kev txhaj tshuaj tam sim no los ntawm cov zis ua haujlwm tau tsawg dua.
