Title: HF or DF Chemical laser using laser induced chemistry

Abstract: A chemical HF or DF laser is obtained by irradiating COF.sub.2 +H.sub.2 /ub.2 in admixture with the R.sub.12 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 COF.sub.2 is mixed with H.sub.2 or D.sub.2 in a properly conditioned system without reacting. The irradiating by the R.sub.12 line of a CO.sub.2 laser dissociates the COF.sub.2 to form CO+2F* (F* --atom in an excited state). The F* atom then reacts with H.sub.2 /D.sub.2 present to produce HF or DF in an excited vibrational state. The halogen containing molecule then lases.
