Webb20 juni 2024 · To have a CO2 laser, a mixture of Co2 and N2 in the ratio of about 0.8:1 is filled in a gas discharge tube. Also, helium is part of the mixture. Helium is more than N2 in the mixture. Co2 molecule act as an active or laser medium and N2 molecule help in achieving the population inversion in the same way as helium is used in He-Ne laser. WebbMost He-Ne laser emit in the red at 633 nm. They are used in interferometers, bar-code reader, and laser printers. They also are used for many sighting and pointing applications from medical surgery to high-energy physics. In a helium neon laser, a low pressure mixture of helium and neon (<15%) is contained in a narrow bore glass tube.
