Research on Fast Beam Alignment Technology at Target Area Based on Swarm Collaboration Control Model

In this paper, in order to reduce the total time for aligning all laser beam of an large-scale laser facility at target area, a fast convergence control mode of beam swarm alignment based on the swarm collaboration control mode was constructed, and a beam alignment fast convergence algorithm was designed on the basis of this model. According to the data which was collected at the facility site and running data in the 8-bundle serial alignment mode, the algorithm was simulated for 20 shots. The simulation results show that the algorithm can greatly reduce the average alignment time of 8 beams, from 233.7s to 162.2s, and the reduction rate is greater than 30%. The algorithm proposed in this paper has a certain reference for the design and engineering application of large-scale laser facility.
