Abstract

Abstract

To study the influence of polarization direction on far field of laser array with coherent combining, an onedimension analyses model of fiber laser array is established, and using Fourier optics, the expression for the far field intensity of coherent combining beams is deduced when the polarization direction of a single cell is deviated. Numerical calculation results show that, with the increasing of the deviation the maximum intensity of center lobe reduces, and the minimum intensity is no longer zero. The deviation of the polarization direction will not change the symmetry of the energy distribution. For the the array with 5 fiber lasers, when the deviation angle is π/2, the peak intensity will reduce to about 68% of the original．
- coherent combining,
- polarization direction,
- center lobe energy,
- maximum intensity
