Over the past 36 years much research has been carried out on Bessel beams (BBs) owing to
their peculiar properties, viz non-diffraction behavior, self-healing nature, possession of well …

Ultrashort laser pulses have revolutionized laser-matter interaction because they can
deposit energy at extremely small scales. High-speed and controlled nanostructuring has …

We report on the development of an ultrafast beam shaper capable of generating Bessel
beams of high cone angle that maintain a high intensity hot spot with subwavelength …

The angular spectrum representation of the vector Bessel-Gauss beam is used for
discussing the connection between the angular spectrum decomposition (ASD) method and …

Ultrafast laser pulses spatially shaped as Bessel beams in dielectrics create high aspect
ratio plasma channels whose relaxation can lead to the formation of nanochannels. We …

The remarkable temporal properties of ultra-short pulsed lasers in combination with novel
beam shaping concepts enable the development of completely new material processing …

This paper presents an efficient method to generate high-order Bessel–Gauss beams
carrying orbital angular momentum (OAM) by using a thin and compact optical element such …

Controlling the formation of high aspect ratio void channels inside glass is important for
applications like the high-speed dicing of glass. Here, we investigate void formation using …

We report on an optical setup to generate multi-Bessel beam profiles combining a refractive
axicon and a spatial light modulator. Based on their particular beam profile, Bessel beams …

A photonic nanojet (PNJ) is a highly confined light beam formed by a transparent particle
under light wave illumination. Here, we propose and numerically investigate the PNJ formed …
