Abstract
Experimental results from the CS2/O2 chemical laser system using both a flash photolysis initiated pulsed laser and a microwave discharge initiated continuous-wave (CW) laser were examined by computer simulation techniques. The comparisons between predicted and observed laser performance led to some conclusions concerning the chemical mechanisms operative in the laser. In particular, the laser pumping step is O+CS yields CO+S followed by the chain-carrying step S+O2 yields SO+O which must be rapid, in agreement with the measurements of Fair and Thrush. The oxygen atom-consuming reaction, O+NO2 yields NO+O2, competes too strongly with the other reaction steps for the photolysis of NO2 to be effective as a power improving technique in the flash photolysis laser.
