The main objective of the scientific work was an experimental and theoretical search of conditions for maximal efficiency of the first overtone FO CO laser and a study of a feasibility of lasing band broadening. In lonin et al, 1997 a comprehensive study of FO CO laser with suppressed fundamental band FB lasing has been done. By using an intracavity spectral filter suppressing FB lasing, output efficiency of 3 and specific output energy of approx. 10 Jl.Amagat were obtained, lasing taking place from 13 -- 11 up to 25 -- 23 vibrational transitions lambda 2.7-3.3 micrometers. Some recommendations were formulated. In particular, there were proposed a decrease of intracavity useless optical lasses.
