Paper Abstract

A large volume of experimental study has been carried out with industrial self-heating sealed-off metal vapor active elements in superradiation regime and with stable and unstable telescopic resonators. Such laser output radiation has been showed to have multibeam structure. The beams partly overlap both in time and space, so conning during their formation in concurrence each other in power. While the resonator beams of small divergences and high coherency are easy to be isolated from the superradiance background, e.g. by diaphragm in the focal plane, spatial separation of high quality beams from each other is, on the contrary, rather difficult, especially at large magnification factors. For example, at the resonator magnification 100 the beams divergences differ 3 times, at magnification 200 they differ 2 times, and 1,5 at magnification 300. In this paper an analysis is carried out targeted to reveal the possible contribution of the resonator different beams into diffractional laser output formation.
