Taw qhia ntawm laser ua haujlwm cov ntaub ntawv
Laser ua hauj lwm cov khoom siv hais txog cov khoom siv uas siv los paub qhov hloov pauv ntawm tus naj npawb ntawm cov khoom tawg thiab tsim kom muaj lub zog loj ntawm cov hluav taws xob muaj zog ntawm lub teeb. Nws qee zaum hu ua laser nce nruab nrab. Lawv tuaj yeem ua cov khoom zoo (siv lead ua, iav), roj (atomic gas, ionic gas), Molecular gases), semiconductors thiab kua. Qhov yuav tsum tau ua kom tau rau lub laser ua haujlwm yog ua tiav ntau ntawm cov feem ntau ntawm qhov kev hloov pauv ntawm cov kev siv zog ntawm nws cov lus hais kom ntau li ntau tau, thiab kom tswj tau qhov kev hloov pauv no kom ua tau zoo thoob plaws ntawm cov txheej txheem laser emission; Txog qhov kawg no, cov khoom ua haujlwm xav tau muaj qhov qauv tsim nyog ntawm lub zog thiab hloov cov yam ntxwv.
