| Abstract: | We present the most important results of investigations of lasers based on vapors and solutions of complex organic compounds.
We investigated the effect of a foreign gas, the duration and intensity of the exciting pulse, the temperature of the active
medium, and the spectroscopic parameters of the material on the generation characteristics of complex molecules in the gas
phase. The special features of generation of radiation by a laser with distributed feedback in transition from a condensed
to the gas phase in heating the active medium are considered. It is suggested that the polarization characteristics of the
radiation generated by a vapor laser be used to investigate the laws that govern the relaxation of optically induced anisotropy
of excited molecules of the active medium.
