Abstract : The authors describe work done under a program to demonstrate feasibility of a supersonic mixing laser using chain reactions of the H2-Cl2 system to produce vibrationally excited HCl. This report describes the experimental setup, test procedures and hardware operation, and results of tests carried out to date. The experiment uses arc heated diluent gas to partially dissociate chlorine. Diluent plus chlorine gas flows through a two dimensional nozzle bank and then mixes with slit injected H2 as a free jet in a stable laser cavity. Three diluents (N2, He, Ar) have been used in the tests with CW laser power measured using the first two. Peak power of 27 mw was detected using He diluent. Previous theoretical analysis predicted much higher powers. The reasons for the discrepancy are discussed and future experiments are suggested. (Author)
