He -ne laser
WebHelium–neon (He–Ne) lasers are a frequently used type of continuously operating gas lasers, which is also the first demonstrated gas laser (already in 1961 [1]). Most often, He–Ne lasers emit red light at 632.8 nm at a power level of a few milliwatts and with excellent beam quality. WebA HeNe laser (also helium-neon laser or he-ne laser) is a type of continuously operating, or continuous-wave (CW) gas laser that uses a mixture of helium and neon gases as the …

As a light source, He-Ne gas lasers and Ar-ion lasers have commonly been used for years. The generated light has a wavelength of 632.8 nm with an output power range of 5–50 mW in a He-Ne laser, and wavelengths of 488 and 514.5 …
WebThe basic principles of laser operation are described by Svelto (1982), and the relevant pages are reproduced in Appendix IV. In a He-Ne laser operating at 632.8 nm there is an inversion of the populations of the (2p)5 5s and (2p)5 3p levels of Ne. The inversion arises principally from inelastic collisions between Ne atoms in WebA single mode He-Ne laser operating at 6328 Å is used with an iodine cell in the cavity to detect the absorption components of iodine falling within the gain curve of the laser line. Experimental details are given for locking the frequency of the laser line with one of the hyperfine components of the iodine absorption line, using a servo-control system. The …
