  • Abstract
    Resonance-enhanced third-harmonic generation (THG) of CO2laser radiation has been studied in CO and NO. It is shown that the coherence length for THG in CO can be increased by adding SF6and that phase matching occurs for a CO:SF6ratio of 208:1. The pressure dependence of the third-harmonic conversion efficiency in CO-SF6mixtures has been measured up to 11 atm, and the results are in good agreement with calculated values for the coherence length and the third-order susceptibility tensor.
