Semiconductor laser, tseem hu ua laser diode, yog lub laser uas siv cov khoom siv semiconductor ua nws cov khoom ua haujlwm. Nws muaj cov yam ntxwv ntawm qhov me me thiab lub neej ntev.Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm semiconductor lasers yog ib txoj kev excitation, uas siv cov khoom siv semiconductor (uas yog, siv cov khoom siv hluav taws xob) rau kev hloov pauv ntawm lub zog hluav taws xob los tawm lub teeb. Lub cleavage nto ntawm lub semiconductor siv lead ua yog siv los ua ob qho tib si thaum uas tig mus tsom iav raws li daim iav los tsim cov kab noj hniav resonant rau oscillate thiab tawm tswv yim lub teeb. Cov hluav taws xob uas tsim lub teeb yog amplified thiab laser lub teeb yog tso zis.
Semiconductor lasers ua haujlwm los ntawm kev txhaj tshuaj, thiab peb cov xwm txheej yuav tsum tau ua kom tau raws li cov lasers:
(1) Nws yog ib qho tsim nyog los tsim kom muaj tus naj npawb txaus inversion kev faib tawm, uas yog, tus naj npawb ntawm cov khoom nyob rau hauv lub zog siab yog txaus loj dua li cov khoom hauv lub xeev uas tsis muaj zog.
(2) Nws muaj qhov tsim nyog resonant kab noj hniav uas tuaj yeem ua lub luag haujlwm tawm tswv yim, ua rau kev loj hlob ntawm cov emission photons, uas ua rau laser oscillation.
(3) Qee qhov xwm txheej yuav tsum tau ua kom lub photon nce sib npaug los yog ntau dua qhov poob ntawm photon.
