Abstract
An efficient procedure for determining the operational potential of a
laser system is the experimental measurement of gain. Two laser systems,
a flowing CO₂-N₂-He laser and a chemical CO₂-HN₃, laser, were studied using
a pulsed gain measurement technique. The experimental investigation
indicated that the flowing CO₂-N₂ -He laser system could produce lasing
action and that the saturation parameter was 15 watts/cm². The experimental
results for the chemical laser show a gain of approximately 8% per meter and
agree qualitatively with a computer model of the CO₂-HN₃ laser. However,
difficulties in obtaining consistent results, which were attributed to
saturation of the lasing medium by the reference signal, and a low signal-to-
noise ratio prevented any final conclusion. Further experimental
investigation of the CO₂-HN₃, laser will be necessary to determine the full
potential of the laser system.
