Abstract

The cw chemical laser generating simultaneously on molecules HF (λ~ 2.7 &mgr;) and HBr (λ~ 4.2 &mgr;) is investigated by means of CFD code based on 2D Navier-Stocks equations. Such laser differs from the conventional cw HF laser by the strong thermal emission. In spite of much weaker gain properties of molecule HBr in comparison with HF it is possible to achieve the HBr laser power ~ 25 W from 1 sm² nozzle bank surface at lasing zone length ~20 sm. The desirable HF/HBr power ratio can be adjusted by bromine dilution of the secondary fuel.
