Description of Interference Theory on Generated Period Bottle Beam by Focus Non-Diffracting Beams
Description of interference theory on generated period bottle beam by focus non-diffracting beams is used. The biggest non-diffracting distance of bottle beam is calculated. The non-diffracting beam focused by axicon is analyzed by geometrical optics theory and interference theory. The intensity distributions along the propagation distance, the intensity evolution of the bottle beams in a complete period and the corresponding spot diagram are simulated by the MathCAD software. In terms of experiments, non-diffracting Bessel beam is generated by an axicon with base angle of 1°, and then is focused by another axicon with base angle of 2°. The beam is observed by a microscope and is photographed by a CCD camera. The experimental results are agree well with theoretical analysis.
