BRIEF COMMUNICATIONS: Feasibility of construction of a chemical H2-Cl2 laser with a chain reaction mechanism
An isothermal model is used to show that in the presence of vibrationally excited hydrogen the chain chemical reaction Cl + H2*→HCl + H, H + Cl2→HCl + Cl can provide an efficient mechanism for pumping an H2–Cl2 laser. A chemical gasdynamic variant with thermal excitation of hydrogen should provide a laser radiation energy of 80–110 J/g at working mixture pressures of ~1–10 Torr in the resonator and 30–70 J/g at pressures an order of magnitude higher.
