Abstract
The beat spectrum between modes of a gas laser having a resonator with a plane-and-sphere mirror system was studied. Intense beats were detected in the 0–1.5 Mc range. It is shown that the presence of low-frequency beats can be associated with the nonideality of the resonator. The intensity of the beats was found to depend on their spectral composition and on the degree of beam limiting. This effect is related to the presence of antiphase oscillation zones in the laser beam for azimuthal modes and to the variation of the interference pattern with time when the beam is limited in the focus of the objective.
