Abstract
Reactions of free atoms in the gas phase play an important part in the development of high power lasers. Investigations of microscopic details of atom reactions led to the discovery of the hydrogen halide and other chemical lasers. Molecules formed in exothermic reactions of atoms often exhibit a strong vibrational and rotational nonequilibrium excitation, which can be converted into stimulated infrared emission. More recently atom reactions which form electronically excited products have become very popular in connection with lasers operating on one or more transitions in the ultraviolet and visible wavelength region. Beside electronically excited molecules the excited atoms itself can also be used in electronic transition lasers.KeywordsHigh Power LaserVibrational ExcitationChemical LaserPotential Energy BarrierSubstantial Potential EnergyThese keywords were added by machine and not by the authors.
