Abstract
Temporal behavior of small signal gain (SSG) for a frequency tunable first-overtone CO laser has been studied both experimentally and theoretically. The laser operates on highly excited vibrational transitions from 20→18 up to 38→36 that correspond to laser wavelength range between ~3 and 4 microns coinciding to atmospheric 'transparency window'. Maximum SSG comes up to 0.4 m-1. It is shown that multiquamtum and asymmetric VV exchange has to be taken into account when analyzing processes of population formation on high vibrational transition.
