Abstract : The objective of this work was to provide preliminary laser performance evaluations for several liquid storable, advanced chemical laser reactant systems. Four advanced reactant systems, F2/MAPPGAS/He, F2/C6F6/He, F2/C7H8/He and F2/C7H8/N2 plus one baseline system F2/C2H2/He were evaluated. Lasing powers between 5 and 8 kw were obtained for all helium diluent systems tested. Significantly lower performance (<3 kw) was obtained with nitrogen diluent. It was concluded that all of the reactant systems tested in this program would provide acceptable performance for combustion driven DF chemical lasers. It was recommended that nitrogen diluent not be used for high pressure nozzles except in cases where helium diluent was unacceptable.
