Conclusion The study performed indicates the important role of the pulling effect of generation frequencies in molecular lasers with resonance optical excitation and is common for pumping transitions and generation by lasing levels. The magnitude of pulling Δω in a model system (NH3 laser) must reach hundreds of megahertz. A feature of the pulse regime is the Se dependence of Δω and the possibility of change of direction of pulling during generation. Besides it was discovered that in similar systems one can control the temporal parameters of the output pulse by changing the tuning of the highly selective resonator containing a Fabry-Perot interferometer. Still another distinct property of the pulse system considered is the fact that for sufficiently intense excitations generation develops at many longitudinal modes, with subsequent displacement of radiation from one mode to another. Account of these effects is particularly important in using laser radiation for selective action on matter and in spectroscopy. To satisfy several problems (spectroscopic for example) the operating regime in which the generation frequency is time dependent may be of interest. Unfortunately, at the present time there exist no experimental studies of output spectral characteristics of molecular lasers with resonance optical pumping in the intermediate IR region.
