Abstract

In erbium - ytterbium fiber lasers with mirrors based on sets of optomechanical microoscillators, modes of multi-frequency (up to five frequencies) synchronous self-oscillations are implemented; microoscillators are made in the form of silicon microbeams array with a quasi-equidistant spectrum of elastic vibration modes excited by laser radiation pressure. A significant dependence of self-oscillations on the spectral properties of optical resonator mirrors has been revealed, which is explained within the framework of the concepts of inhomogeneous broadening in the active fiber.
