Abstract
Laser emission from vibrationally excited HCl has been achieved in a transverse flow system whose pumping energy relied upon the reaction Cl + HBr yields HCl + Br. For these experiments the chlorine atoms were produced in situ from the chemical reaction of NO with ClO2. The observed maximum output power of 0.34 W was approximately one third the output power if hydrogen iodide was substituted for HBr. Loss of HCl vibrational quanta through collisions with HBr is believed to be a severe limitation on Cl + HBr system and probably accounts for the reduced HCl laser efficiency of Cl + HBr compared with Cl + HI along with the reduced exothermicity of the pumping reaction.
