Abstract

The characteristics of fiber laser coherent beam combination are investigated by using a 2×2 fiber laser array with a self-Fourier cavity. The experimental results show that with a certain output width the power ratio of the center spot is increased with the increase of space duty cycle, meanwhile the number of secondary spots is decreased correspondingly. The results are in agreement with theoretic analysis.
