Abstract

We simulated beam combination of Yb-Doped Double-Clad-Fiber(DCF) lasers theoretically by using a new external cavity and this system suits both of 1D array and 2D array. The numerical simulation result of 1D linear array shows that light energy from fiber lasers can be coupled into fiber cores through a single round trip. In comparison with several 2D arrays, we find that both the radius of the central spot shroten with the number of fibers increasing, on the contrary, the optical feedback through a single round trip coupled into cores increase gradually.
