Abstract:

Recent data for the vibrational energy exchange rates associated with CO2-N2-H2O gas lasers are compared with previous compilations. From this, current uncertainties in the rate data are established. Using an existing computer code, a study is made of the sensitivity of gasdynamic laser performance to these uncertainties. The results show that present-day calculations of gasdynamic laser gain and maximum available power are subject to at least a 25 percent inaccuracy due to such rate data uncertainties. Author
