Abstract :
The afterglow pulse-gain technique was used to measure the relaxation of the 00°1 upper laser level in N2 O from 300 to 700°K. The rate constant 
(torr-1s-1) varies with temperature as 
10 
. Measurements of the relaxation time at 300°K agree with the fluorescence technique results of Yardley [1]. Gain studies were also made with gas mixtures in a nonflowing system. Single-pulsed N2 O + CO + He mixtures at 300°K 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.
