Abstract

With multipulse energy extraction in electric discharge excited CO2-laser amplifiers, we can convert a significantly higher fraction of the vibrational energy stored in the gas by the discharge into laser light. The time scale for efficient energy extractions is determined by the collisional transfer rates for the flow of vibrational energy into and among the various vibrational modes of the gas molecules. We briefly survey the collisional processes of interest, describe optical techniques of implementing the multi-pulse method, and give calculated results for a representative case. The results indicate that high laser efficiencies, attractive for future commercial applications, can be achieved with CO2 lasers.
