Excimers important commercial

The wavelength of the emitted light depends on the choice of atoms A and B. Besides the principle of excimer formation, the technical parameters for the lamp and discharge are responsible for the quasi-monochromatic character of the emitted spectrum. The most important commercial excimers are formed by electronic excitation of molecules of rare gases (He2, Ne2, Ar2, Kr2, Xe2),... 

Gas Lasers. A variety of ga.s lasers is available commercially. These devices are of four types (1) neutral atom lasers such as He-Ne (2) ion lasers in which the aciive species is Ar or Kr (3) molecular lasers in which the lasing medium Is CO, or Nil and (4) excimer lasers. The helium-neon laser is the most widely encountered of all lasers because of its low initial and maintenance costs, its great reliability, and its Kivv H)wcr consumption. The nuist important of its output lines is at 6.32.8 nm. It is generally operated in a continuous mode rather than a pulsed mode.
