摘要
For studying the polarization in laser beam coherent combination, ideal rectangular beams are used in simulation. With changing the degradation rate of polarization, the angles between beams' axes and the number of combining beams, the synthetic effects of the laser fields are observed. And the far-field intensity distribution, the peak power and the beam quality of the combined beams are analyzed. Results show that if the degradation rate of polarization is less than 10% or the polarization angle is less than 18 degrees, the beam quality factor of combined beams could be controlled in 1.1 times the diffraction limit.
