Research on paraxial propagation behavior in radially polarized vector coherent array laser beams [Early Posting]
This paper reveals the propagation dynamics behavior of radially polarized vector coherent array laser beams. The results show that due to the asymmetric polarization coupling of the beam, the far-field intensity distribution is an ordered linearly polarized Gaussian-like sidelobes array. Furthermore, the programmable control of the polarization direction and intensity distribution of the far-field by adjusting the beamlets polarization and array arrangement, which provides a feasible path for the structured output of the vector light field. This study fills the gap in the propagation dynamics of vector coherent array laser beams, and also provides theoretical support for space optical communication, structure light applications.
