Title: HCl or DCl Chemical laser using laser induced chemistry

Abstract: A chemical HCl or DCl laser is obtained by irradiating COCl.sub.2 +H.sub.2 D.sub.2 in admixture with the P.sub.54 line of a CO.sub.2 laser. The irradiation is accomplished in a laser cavity provided with appropriate Brewster windows, mirrors, and coupling means. The COCl.sub.2 is mixed with H.sub.2 or D.sub.2 in a properly conditioned system without reacting. The irradiating by the P.sub.54 line of a CO.sub.2 laser dissociates the COCl.sub.2 to form CO+2Cl* (Cl*-atom in an excited state). The Cl* atom then reacts with H.sub.2 /D.sub.2 present to produce HCl or DCl in an excited vibrational state. The halogen containing molecule then lases.
