ARPA-NRL Laser Program - Semiannual Technical Report to Defense Advanced Research Projects Agency, 1 January 1974-30 June 1974

Abstract

The ARPA-NRL 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 focussed on DF-CO2 supersonic transfer laser experiments designed to evaluate chemical augmentation of gas dynamic lasers. Augmentation has been observed but is limited by deactivation processes. The temperature dependence of energy transfer processes in CO, CO2, and N2O has been measured. The Electrical Infrared Laser Program has two primary projects, short-pulse CO2 laser technology and electric-discharge gas dynamic lasers (EDGDL). The short pulse laser project has successfully been completed culminating in reliable 70 J single-pulse operation. A compact high-pressure e-beam-controlled CO2 laser has been developed for the generation of picosecond laser pulses. Infrared fluorescence from HCl generated by energy transfer from vibrationally excited D2 has been measured.
