Abstract : An analytical treatment of diffusion-type chemical lasers is presented. Chemical formation of the lasing molecule by laminar mixing and combustion of parallel streams of fuel and oxidizer is assumed to be diffusion controlled, and subsequent collisional deactivation of each vibrational level of the lasing molecule by nonreactive V-V and V-T energy transfer is found by a successive-approximation scheme. Radiative processes are considered only in zero-power an high-power limits. A laser employing the reaction H2 + F yields HF(v) + H is considered in detail with the use of a single-boundary-layer, flame-sheet model. Expressions for integrated zero-power gain, laser power, and efficiency are obtained. (Author)
