Paper Abstract

Parametric study of first overtone (FO) CO laser was carried out both experimentally and theoretically. Special optical filter was used for suppression of fundamental band lasing. The theoretical model is in satisfactory agreement with the experiment for the laser operating on He-containing gas mixture. The maximum FO CO laser efficiency of 5.5% and specific output energy of approximately 20 J/I Amagat were obtained for laser resonator with rather high useless optical losses, FO CO lasing taking place from 13 yields 11 up to 30 yields 28 vibrational transitions ((lambda) equals 2.7 - 3.6 micrometers ). Important influence of intracavity water vapor on output characteristics of FO CO laser and its spectrum, in particular, is discussed. Both theoretical and experimental results indicate that FO CO laser efficiency up to 15 - 20% and SOE up to 50 - 80 J/I Amagat can be obtained.
