HeNe Laser SystemsHeNe laser systems are optoelectronic devices that generate a beam of laser light at a wavelength of 632.8 nm. HeNe lasers are commonly used in applications such as spectroscopy, metrology, and alignment, where their high coherence and monochromaticity are advantageous. HeNe laser systems typically consist of a helium-neon (HeNe) gas laser tube, a power supply, and a beam delivery system. The HeNe gas laser tube is the heart of the system, and it generates the laser light by stimulating atoms of helium and neon with an electric current. The power supply provides the electrical energy needed to operate the laser, and the beam delivery system shapes and directs the laser beam.
