Negative CO2 laser efficiency behavior as a function of coolant temperature and gas composition
Abstract
An analysis of CO2 laser efficiency under the combined effects of variation in N2 partial pressure in the gas mixture and coolant temperature is presented. For particular CO2:N2 ratios, results show that efficiency decreases as the gas kinetic temperature decreases. A competition between gas and electron temperatures is pointed out as responsible for the effect.
