摘要：
We introduce a novel algorithm used in coherent beam combining: double stochastic approximation based on logic comparison (DSAL). Both the theoretical investigation and the numerical simulation indicated that the DSAL method can be convergent efficiently. The coherent beam combining of two W-level fiber amplifiers experiment shows that the whole system in close-loop performs well for long-time observation and nearly 72% combining efficiency was realized. In the further experiment with some improvement, the combining efficiency increased to 81%. This algorithm has widely potential application in coherent beam combining field.
