Experimental and Theoretical Search of Conditions for Maximum Efficiency and for Frequency Tunability of IR Overtone CO Laser. Phase 1

Abstract

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 J/l.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.
