Helium-neon (HeNe) lasers have been a mainstay of flow cytometry almost since their introduction (Hoffman et al., 1987; Shapiro, 1986; Shapiro and Stephens, 1986). LASERS. Example 1. Consider a HeNe laser in which the mirror reflectivities might be R1 = 0.999 For the HeNe laser given in Example 1, assume that the gain is 10 times the threshold value or g = 10 Single transverse mode oscillation is realized in a conventional HeNe laser outside the stability region of the optical resonator. Depending on the mirror separation different spatial modes can be generated. Sam's Laser Power Meter 2 (SG-PM2) (sgpm2sch.pdf).

A description of the rather complex HeNe excitation process can be given in terms of the Building a HeNe Laser Kit: This is about building a Class II <1mW Helium-Neon (HeNe) laser. Well wouldn't you know they sent me a PDF of the schematics and instructions the very next day! The HeNe Laser may work at different wavelengths.There are infrared transitions at 3,39 m and 1,15 m and different transitions in the visualspectrum.

Conclusions This research shows there is a detectable, intrinsic signal in a three mode HeNe gas laser which can be used for feedback stabilization. A helium-neon laser or HeNe laser is a gas laser consisting of a mixture of neon and helium within a small bore capillary tube, which is excited by a DC electrical discharge.
