Measurements of dissociation efficiency of molecular chlorine through microwave discharge

For the system of Cl/Cl2/HN3/He which is the basis of concept of NCl(a1Δ)/I as a newly possible laser system, the amount of the production of chlorine atoms is essential and important to the system. In this paper, the dissociation efficiency of chlorine by a Microwave Generator is investigated by a versatile titration technique. The intensity of NCl(a1Δ) and NCl(b1Σ) emission is monitored by an OMA with the titration of mixture of He and HN3. The dissociation efficiency of chlorine by Microwave Generator is not low as expected, it is up to 100% at lower flow rate of chlorine and decreases with increasing chlorine flow rates.
