The He is usually used as diluent in combustion cw hydrogen/deuterium fluoride (HF/DF) chemical lasers. Sometimes the N{sub 2} is also used as diluent in cw HF/DF chemical laser because N{sub 2} is cheaper than the He. It was thought that the efficiency of cw HF/DF laser with N{sub 2} diluent was lower than that of HF/DF laser with He diluent since the molecular weight of N{sub 2} is heavier than that of He. In this paper, the performance of cw DF chemical lasers with He and N{sub 2} diluent was investigated. The small signal gain, power spectral distributions, cavity pressure, power and the efficiency of DF lasers with these two diluents have been calculated using a finite-difference technique for the numerical integration of the steady and unsteady Navier-Stokes equation with reactive flow (compressibility scaling method -- CSM), which was developed in the chemical gas dynamic laboratory of the state institute of applied chemistry in Russia. The numerical results show that the efficiency of DF lasers with Na{sub 2} diluent is not lower than that of the lasers with He diluent.
