Helium neon wavelength

WebA helium-neon laser, usually called a HeNe laser, is a small gas laser. Its usual operation wavelength is 632.8 nm, in the red portion of the visible spectrum. Construction: Working: It is the most common type of laser used in physics laboratories. Its discharge tube is fitted with 80% helium and 20% neon gas. WebII. THE HELIUM-NEON LASER In a helium-neon laser the He atom is excited by an electrical discharge. Collisions of the second kind be-tween helium and neon atoms ensure the required popu-lation inversion between the neon energy states. A sec-ond kind collision is a process where the energy of a metastable state of one gas lies very close to the ...
