With the invention of chirped pulse amplification for lasers in the mid-1980s, high power
ultrafast lasers entered into the world as a disruptive tool, with potential impact on a broad …

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 …

This article presents a study of the electrophysical properties of a piezoceramic material for
use in adaptive optics. The key characteristics that may be important for the manufacturing of …

Helical structures exhibit novel optical and mechanical properties and are commonly used in
different fields such as metamaterials and microfluidics. A few methods exist for fabricating …

We present partially coherent sources that are statistically twisted in the space-frequency
and space-time domains. Beginning with the superposition rule for genuine partially …

It is well-known that the wave of a freely propagating Gaussian beam experiences an
additional π phase shift compared to a plane wave. This phase shift, known as the Gouy …

We demonstrate an alternative approach for generating zeroth-and first-order long range
non-diffracting Gauss–Bessel beams (GBBs). Starting from a Gaussian beam, the key point …

Over the past few decades, remarkable breakthroughs and progress have been achieved in
ultrafast laser processing technology. Notably, the remarkable high-aspect-ratio processing …

Many applications ranging from nonlinear optics to material processing would benefit from
pulsed ultrashort (quasi-) non-diffracting Gauss-Bessel beams (GBBs). Here we …

Microfabrication based on photopolymerization is typically achieved by scanning a focal
spot within the material point by point, which significantly limits fabrication speed. In this …
