The ARPA-NRL High Energy Laser Program is concerned with the development of laser technology in three project areas Chemical Infrared Lasers, Electrical Infrared Lasers and Electronic State Lasers. The Chemical Infrared Laser Program is concerned with the developement of the DF-CO2 supersonic transfer chemical laser, the study of the CO vibrational distribution from exothermic reactions which produce CO and the measurement of energy transfer rates of CO. The objective of the DF-CO2 program is the chemical augmentation of gasdynamic CO2 lasers. V-V and V-R,T energy transfer rates have been measured for CO-additive mixtures and the temperature dependence of some of these rates has been investigated. The Electrical Infrared Laser Program consists of two primary projects, short-pulse CO2 laser technology and electric- discharge gasdynamic lasers EDGDL. Advances in pulse switch out technology and measurements of gain profiles and spectral content are reported. Components for an EDGDL apparatus for the investigation of the D2 - HCl transfer laser have been fabricated and are being assembled.
