What is it about?
For the first time, a stable “helical polarization distribution” Bessel beam was generated by using a fs laser structured glass plate. Besides, such a z-variable-polarized laser beam was implemented for laser materials processing namely to imprint "twisted silica glass".

Why is it important?
We proposed a novel concept to extend the polarization manipulation along the optical path, which provides new perspectives in polarization transformation and therefore, enriches the state of the art of light manipulation. As a demonstration, this structured light beam was exploited to imprint chiral optical properties in a glass.
