A New Beam Combination of Fiber Laser Array

Coherent beam combination of fiber laser array is an important technology in realizing high power fiber laser system. This paper designs a simple and effective method to get more concentrated laser intensity distribution and higher peak power in the far-field. The difference from previous designs is the focusing beams combination scheme is adopted. Compared with the traditional one, it gets the meaningful conclusion. At the same time, the effect of fill factor on conversion efficiency was analyzed in detail.
