Taw qhia rau Helium-neon roj laser
Lub helium-neon laser yog cov roj laser uas siv qhov nruab nrab atomic gases helium thiab neon raws li cov khoom siv ua haujlwm. Qhov nruam laser yog tsim tawm nyob rau hauv hom kev zam txuas ntxiv. Hauv thaj chaw pom thiab ze-infrared, muaj feem ntau peb kab ntawm 0.6328 microns, 3.39 microns thiab 1.15 microns, ntawm cov teeb liab liab ntawm 0.6328 microns yog qhov feem ntau siv. Lub zog tawm ntawm helium-neon lasers feem ntau yog ob peb milliwatts rau ntau pua milliwatts
