  • RP Photonics Encyclopedia - Helium-neon lasers, He-Ne ...

    Helium–neon lasers, particularly the standard devices emitting at 632.8 nm, are often used for alignment and in interferometers.They compete with laser diodes, which are more compact and efficient, but have less convenient beam profiles.. Some He–Ne lasers are serving in optical frequency standards.For example, there are methane-stabilized 3.39-μm He–Ne lasers, and 633-nm iodine ...

  • Helium–neon laser - Wikipedia

    A helium–neon laser or He-Ne laser, is a type of gas laser whose gain medium consists of a mixture of 90% helium and 10% neon at a total pressure of about 1 torr inside of a small electrical discharge.The best-known and most widely used He-Ne laser operates at a wavelength of 632.8 nm, in the red part of the visible spectrum.
