WebbThe He-Ne laser consists of a mixture of He and Ne in a ratio of about 10:1, placed inside a long, narrow discharge tube (see Figs. 26.20 and 26.21). The pressure inside the rube is about 1 torr. The gas system is enclosed between a pair of plane mirrors or a pair of concave mirrors so that a resonator system is formed. A helium–neon laser or He-Ne laser, is a type of gas laser whose high energetic medium gain medium consists of a mixture of 10:1 ratio of helium and neon at a total pressure of about 1 torr inside of a small electrical discharge. The best-known and most widely used He-Ne laser operates at a wavelength of … Visa mer The first He-Ne lasers emitted infrared at 1150 nm, and were the first gas lasers and the first lasers with continuous wave output. However, a laser that operated at visible wavelengths was much more in demand, and a … Visa mer Red He-Ne lasers have an enormous number of industrial and scientific uses. They are widely used in laboratory demonstrations in the field of optics because of their … Visa mer The gain medium of the laser, as suggested by its name, is a mixture of helium and neon gases, in approximately a 10:1 ratio, contained at low pressure in a glass envelope. The gas mixture is mostly helium, so that helium atoms can be excited. The excited … Visa mer • List of laser types Visa mer
