In this work, we present efficient generation of a high-quality vector Bessel beam using an S-
wave plate (radial/azimuth polarization converter) together with an ordinary glass axicon …

The control of laser-induced microcracks in the volume of transparent materials is essential
for scribing processes. In this paper, we investigate the effect of various amplitude and …

Here, we present thorough research into high-order vector Bessel-Gauss beams from a
theoretical perspective, with experimental realization and application to transparent-material …

Conventional processing tools of glass cannot fulfil the forever increasing industrial
requirements for processing speed and quality. In the future these methods can be replaced …

The extended focal depth of Bessel beams is a very attracting property for glass cutting
applications. However, Bessel beam generation with a non-ideal conical lens induces beam …

Non-diffracting Bessel beams and its modified versions are widely used in industry for
transparent material micro processing purposes-cutting, drilling etc., due to generation of …

Nondiffracting beams are known for their long line of focus, which has various applications
in laser materials processing. Zeroth order Bessel beam is usually generated with an axicon …

It is known that Bessel beam generation with a non-ideal axicon induces beam pattern
distortions. In this paper, we introduce a simple method for non-ideal axicon-generated …

Invariant Bessel–Gauss beams have attracted great interest for transparent material
microprocessing applications. The small central peak and elongated focal region of the …

The modification of transparent materials is enabled by focused ultrashort laser pulses.
Single pass processing up to several millimeters can be achieved by the usage of elongated …
