摘要：
The implementation of an axicon array is proposed for generation of regularized multiple laser filaments. The results of numerical simulations demonstrate that the transverse patterns of multiple filaments are determined by the arrangement of the axicon array. Parallel filaments are generated by each axicon unit. Meanwhile, it is shown how the the length of filaments can be increased.
