Helium-Neon Lasers
A helium-neon (henceforth abbreviated HeNe) laser is basically a fancy neon sign with mirrors at both ends. Well, not quite, but really not much more than this at first glance (though the design and manufacturing issues which must be dealt with to achieve the desired beam characteristics, power

Laser Trackers
and a frequency-stabilized, helium-neon. laser. The laser light splits into two beams. One travels directly into the interferometer. The other beam. travels out of the tracker, reflects off the SMR and, on the return path, passes into the interferometer. Inside. the interferometer, the two beams of light
