A supercontinuum bottle beam was successfully produced by
focusing a supercontinuum laser beam after passing through an axicon.
The supercontinuum radiation was generated from a microstructured fiber
pumped by a self-kerr-lens mode-locked femtosecond Ti:sapphire laser.
The cross-section intensity distributions of the generated bottle were
recorded by a beam profiler. Using the line filters to select different
central wavelengths, the different colors of bottle beams show slightly
different bottle ranges and diameters due to the dispersion of axicon and
focusing lens. The results consist with the theoretical prediction using the
Fresnel-Kirchhoff’s formula in considering an incident Gaussian beam.
