Abstract: A chemical laser including a laser pump which is relatively lightweight with no moving parts is provided. This produces a low pressure, regenerable, closed system for treating laser cavity exhaust gases to remove (i.e., pump) them from the system.The exhaust gases which emerge from the laser cavity of the chemical laser are pumped by a combination of condensation, cryogenic adsorption, and by reaction preferably with titanium, titanium-zirconium alloys, zirconium, tantalum, etc. These exhaust gases include hydrogen, deuterium and their halides, the halogens, oxygen, CO.sub.2, nitrogen and H.sub.2 O. This obviates the requirements for heavy equipment normally employed to produce a high vacuum in the laser cavity.

Abstract: A process for producing improved chemical laser absorbent materials by prpitating the chemical laser absorbent materials of metal from liquid anhydrous ammonia at very low temperature to produce an absorbent material that has a high surface area and when desired to deposit the chemical absorbent material on a substrate material in the process of precipitating the absorbent material from the liquid ammonia. The chemical metal absorbent material is adapted for containment of the effluent gases from a chemical laser and the substrate when used absorbs the heat of reaction.
