The propagation of the light beam emitted by a vertical-cavity surface-emitting laser array is numerically simulated in a system, in which the beam is modulated by a phase-only diffractive optical element. The element designed by means of combining simulated annealing algorithm and block iterative projections algorithm can focus the beams array into a narrow peak with low background and keep it in a longer distance without diverging.
