The invention discloses a laser particle control method, comprising the steps of adopting reverse learning to conduct initialization on a unit coordinate in a cluster; introducing IRICP vector searching method to find an optimal laser particle control unit; conducting Laplace chaotic interference on the optimal laser particle control unit in the current cluster, obtaining the optimal unit of the optimal laser particle in the cluster. The invention is advantageous in that during the comparison of adaptability in each round, the laser particles corresponding to the multiple clusters can be compared with each other, and laser particles in one cluster can be compared with each other, and thereby the demand of precision control can be met.
