Abstract : The afterglow pulse-gain technique was used to measure the relaxation of the upper laser level in N2O from 300 to 700K. Measurements of the relaxation time at 300K agree with the fluorescence technique results of Yardley. Gain studies were also made with gas mixtures in a non-flow system. Singly pulsed N2O + CO + He mixtures at 300K showed considerable peak gain. However, subsequent pulses of these mixtures show that the gain is reduced because of the chemical reaction forming CO2. Measurements of this transformation from one molecular laser mixture to another are discussed. (Author)
