Abstract : The report describes 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. The report describes both DF and HCl laser experiments to determine the cause of low HCl power formerly observed. A factor of 50 improvement in power was obtained with a peak of 0.93 watts cw. Chain lasing occurred at a cavity pressure as high as 25 torr on transitions P2(7) through P2(10). Further improvement in the power is limited by collisional deactivation, primarily that due to Cl atoms. (Modified author abstract)
