Helium-neon laser at the University of Chemnitz, Germany. A helium-neon laser or He-Ne laser is a type of gas laser whose high energetic gain medium consists of a mixture of helium and neon (ratio between 5:1 and 10:1) at a total pressure of approximately 1 Torr (133.322 Pa) inside a small electrical discharge.The best-known and most widely used He-Ne laser operates at a center ...
Learn about the basics of HeNe lasers, their wavelength, linewidth, polarization, and applications. Find out how to choose and use HeNe lasers for various scientific and industrial purposes.
HeNe lasers are preferred for many optics lab applications due to their ease of operation and low cost compared to other laser types. Whether you need the flexibility of multiple wavelengths from a single laser, the stability inherent in an atomic transition, or the confidence that comes from keeping an established process, there are many ...
Lumentum manufactures HeNe lasers in the red wavelength using our close-cathode design that rapidly and uniformly distributes discharge heat throughout the laser, resulting in excellent thermal, beam-pointing, and power stability. Our field concentrator design ignites the discharge within milliseconds of applying the start voltage.
