Abstract:

An analytical model for estimating the minimum requirements of a chemically pumped electronic laser is developed. From a knowledge of the basic spectroscopic and thermodynamic properties of a particular reaction, the model can quickly classify the system according to the feasibility of generating stimulated emission at different possible wavelengths. Sample calculations of the reactions of barium atoms with nitrous oxide and nitrogen dioxide show that the model is sufficiently sensitive to distinguish between very similar systems and therefore should be useful in providing classification criteria in the search for a chemically pumped electronic laser.
