Abstract

Abstract

A Gaussian beam combination model of rectangular array was established. By numerical analysis method, influences of beam separation distance, characteristics of unit beam and array structure on far field peak intensity and beam quality of incoherent combination and the same phase coherent combination were researched. Some results generated by the different phase coherent combination were described, and the features of coaxial combination, non-coaxial combination, incoherent and coherent combination were discussed. The results show that beam quality of incoherent combination and the same phase coherent combination deteriorate with the increase of the unit beam number as well as the ratio of beam separation distance to unit beam waist. For the different phase coherent combination there are s
- laser technology,
- gaussian beams,
- beam combination,
- coaxial coherent combination,
- m2 factor,
- peak intensity
