Abstract

The combustion-type CO//2-gas dynamic laser has the merit of a readily obtainable high input energy, because it can use chemical reaction energy. In this type of GDL, however, impurities such as CO and O//2 which result from imperfect combustion are present in the laser medium. Experimental studies of the influence of these impurities on CO//2-GDL performance are presented. CO and CH//4 fuel is burned with air and N//2 is added to form high temperature (1500 k) CO//2-N//2-H//2O gas mixtures. All the observed impurities were CO and O//2. Both gain and power decreased monotonically with the increase of CO mole fraction up to 10%. The mole fraction of O//2 was always approximately 0. 5% and higher levels of O//2 fraction led to unstable combustion.
