Applying the autosynchronization of waves to amplify laser radiation in waveguides

The possibility of applying the phenomenon of autosynchronization of waves in tunnel-coupled optical waveguides to amplify the laser radiation is considered. An optical amplification method of high-power laser radiation, which includes division, amplification in each channel, and the addition of amplified waves, is proposed. It increases the formation rate of the amplified directed radiation. In the proposed method, the optical waves propagate along optical waveguides made so that the tunnel optical coupling occurs between them, and these waveguides are nonlinear-optical. This method is applicable for the synchronization (phasing) of waves in fiber-optic light guides with many cores in conditions of amplifying these waves. For example, this method can be applied in erbium amplifiers with many cores.
