The role of helium in helium-neon laser​ is:

  • In a He-Ne laser, the Helium gas increases the efficiency of the lasing process.
  • Helium is extremely valuable due to two factors:
  • Direct excitation of Neon gas atoms is inefficient, while it is quite efficient for He gas atoms.
  • The energy level of an excited state of the He atom (labeled E5) is extremely close to that of an excited state of the Neon atom (also labeled E5).
  • The excitation of the Neon atoms takes place in two stages:
  • Electrons accelerate from the cathode to the anode due to the high voltage.
  • When these electrons hit with He atoms, kinetic energy is transferred to them.
