HCL chemical laser action has been obtained from chloro compounds when HI was used as the source of H atoms. Laser action was produced on severalupsilon = 3-2, 2-1, and 1-0 HCl transitions when initiated by transverse pulsed discharges in HI-He mixtures containing such chloro compounds as CCl4, CHCl3, and several Freons. Both HCl and HF lasing were observed when a Freon (C2Cl2F4) containing F as well as Cl was used. The measured wavelengths for these HCl lasers correspond to excellent atmospheric windows for transmission of infrared radiation. No HCl lasing was obtained when HBr, H2S, or H2were substituted for HI.
