Abstract: For the practical applications of DF chemical lasers, we must deal with technologies to densify and to stockplie the laser reactant gases for convenient use and to dispose of the exhausted laser gases by way of chemical absorption. It is feasible for the chemical laser in its potential use with Nitrogen as diluent.
The endeavours to replace Helium with Nitrogen as diluent for the DF chemical laser are described in this essay. It also gives the theoretical analysis and the comparisons of the chemical laser with two different kinds of diluents: Helium and Nitrogen. The experimental results show that the laser output performance with Helium as diluent is better than that with Nitrogen as diluent. But the comprehensive comparisons proved that the laser with Nitrogen as diluent is an ideal candidate for practical use.
