Abstract:

Laser emission from vibrationally excited HCl has been achieved in a transverse flow system whose pumping energy relied upon the reaction Cl HBr yield HCl Br. For these experiments the chlorine atoms were produced in situ from the chemical reaction of N0 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 reactio.
