Abstract

We present a method for the coherent coupling of single-mode fiber lasers that produces a single Gaussian output beam. The output and the spectral properties of an experimental device composed of three coupled Nd³⁺ single-mode fiber lasers have been studied. For different coupling conditions, typically 70% of the total output power has been produced in a single beam. The dynamic behavior of the emission spectrum is discussed.
