The Influence of Vectorial Effect on the Non-Paraxial Propagation of Ultrashort Pulsed Beam in Free Space
Starting from the intrinsically vectorial non-paraxial propagation equations,and employing the Fourier transforming and the angular spectrum formalization,the influence of the vectorial effects on the non-paraixal propagation of ultrashort pulsed beam in free space is analyzed. The result shows that the non-paraxial correction is greatly influenced by the vectorial effect. While the non-paraxial propagation of pulsed beam is dealt,the vectorial effect should be considered. Based on the above analyses,An integral solution of the vectorial non-paraxial propagation equations is obtained. Then an correspondingly simple approach to the vectorial non-paraxial correction to the paraxial pulsed beam solution is developed by use of a Taylor expansion.
