Beam Quality of Partially Coherent Combining of Laser Array
Due to the partially coherence property of single laser beam and bandwidth of phase control system,partially combination is often obtained in coherent beam combining of high power lasers. The propagation property in free-space of partially coherent laser array in the case of residual phase error is analyzed,and the analytical expression of far-field intensity distribution is deduced. The influence of coherence of single laser beam and residual phase error on the combined beam quality is studied.
