Influence of Astigmatism on Periodic Bottle Beam
Periodic bottle beams can be generated by a line focusing Bessel beam illuminated on an axicon, the influence of astigmatism introduced by elliptical manufacture error and oblique illumination on the bottle beam generated by line focusing Bessel beam using axion is analyzed in terms of Fresnel-Kirchhoff diffractive theory. The influence of astigmatism on the bottle beam is not big and the bottle beam still keeps its periodicity and ring closed characteristic, as long as the astigmatism is limited in a small range. The larger the base angle or the refractive index of the axicon is, the smaller the range is, and the more susceptible to the astigmatism introduced by the elliptical manufacture error and oblique illumination the bottle beam is. The result may serve as a guideline in the application of the periodic bottle beam.
