Effect of Mixing Rate on HF Chemical Laser Performance.
A simple model of a steady-flow HF chemical laser has been formulated in which the excited-state formation rate is limited by the H(2)-F mixing rate. Lasing is allowed to take place between several vibrational levels of the HF molecule simultaneously. With reasonable approximations, the power output and efficiency can be determined analytically. The dependence of these variables on the independent parameters is in qualitative accord with experimental observations on mixing lasers but differs markedly from the predictions for lasers in which the reactants are premixed.
