THz lasers with optical pumping (THz OPL) are successfully used in the diagnostics of high-temperature plasma, magneto-polarimetry and spectroscopy of semiconductors, measurement of the parameters of polymeric materials, medicine and biology. Open and waveguide resonators are an effective means of rarefaction of the spectrum, which made it possible to achieve well-known successes in laser technology. For many scientific and applied applications, a given form of the transverse spatial distribution of the output beam field is required, different from the Gaussian mode distributions of quasi-opti...
