利用Richarda-Wolf矢量衍射积分公式,获得矢量偏振贝塞耳-高斯光束经具有初级慧差的高数值孔径系统聚焦后的三维光场复振幅函数,模拟了不同慧差系数下聚焦光场的纵向分布,以及焦平面和光轴上的光强.研究表明,初级慧差的存在导致矢量偏振贝塞耳-高斯光束的会聚光场发生偏移和变形,焦平面光强的分布和光轴上的光强峰值都受初级慧差和入射光偏振态的共同影响,偏振态和初级慧差不影响聚焦光场在光轴上的对称分布.

Using Richards-Wolf vectorial diffraction integral, three-dimensional light field complex amplitude function was derived when vectorial polarized Bessel-Gaussian beam passed through a high numericalaperture system with primary coma aberration. In the case of radially and azimuthally polarized BesselGaussian beam, focused optical field was simulated under different comatic aberration coefficients. The results show that the presence of primary coma produces a positional shift of the high intensity lobes and make the intensity distribution transformed in the high focused optical field, and the intensity distribution on focal plane and light maximum along the optical axis depend on primary coma and polarization. In the case of intensity distribution along the optical axis, polarization and primary coma aberration doesn't change its symmetry.
