Chain-reaction chemical lasers for the visible range

The development of a chain-reaction chemical laser for the visible range utilizing chain reactions is discussed. Radicals (active reaction centers) are proposed as the active particles and the lower laser level is depopulated as a result of a chemical reaction. An analysis of the kinetics of the H₂+NF₂ chain reaction indicates that it is possible to obtain lasing due to electronic transitions in the NF molecule.
