Multiple beam generation and adaptive control plays an important role in the laser propagation applications. The existing approaches are usually mechanical, so they have many limitations in terms of accuracy, bandwidth, and flexibility. In this paper, a kind of dynamic multiple beam forming method based on the fiber laser phased array (FLPA) is proposed. In this method, the FLPA based on the multi-objective optimization algorithm is employed, which can theoretically generate any number of outgoing beams, and dynamically adjust the power of each beam. The numerical simulation experiments based on a 19-cell FLPA were conducted. The results show that two stable outgoing beams of FLPA can be generated after about 200 iterations, and the power distribution error of the two beams can reach less than 4%. In addition, the two beams can also be combined into one after about 50 iterations.
