摘要：

Coherent and incoherent combinations of off-axis Gaussian beams with rectangular symmetry have been studied in detail. The analytical and numerical calculation results have been given to illustrate the propagation properties of the resulting beam through a first-order optical ABCD system. A comparison of the M-2 factor and power-in-the-bucket curve has shown that the main advantages of the coherent combination of off-axis Gaussian beams are the improvement of the beam quality and the increase of the centerline irradiance in the far field of the resulting beam.
