What is a He-Ne Laser:
A helium neon laser (i.e. HeNe laser, he-ne laser) is a type of continuously operating, or continuous-wave (CW) gas laser. A gas laser light source produces a laser beam by applying a high voltage electrical discharge through a gas (e.g., CO2, Helium-Neon, or Argon-Ion). The gas laser was the first continuous operation laser and the first laser to operate by converting electrical energy to a laser light output.
The gain medium is a 10:1 gas mixture of helium and neon, pressurized within a glass tube. Applying a DC current to electrodes on opposite ends of the HeNe tube excites helium gas atoms into metastable states. Thus, when excited, helium atoms can efficiently transfer energy to neon atoms with quite similar excitation energies leading to population inversion. Due to the multiple energy levels of neon gas atoms, multiple laser transitions (helium neon laser’s emitted wavelengths) are possible, providing green HeNe lasers, yellow HeNe lasers, red HeNe lasers, and even IR HeNe lasers.
