Non‐Gaussian beam profiles such as Bessel or annular beams enable novel approaches to
modifying materials through laser‐based processing. In this review paper, properties …

Ultrafast laser 3D lithography based on non-linear light–matter interactions, widely known as
multi-photon lithography (MPL), offers unrivaled precision rapid prototyping and flexible …

Tunable-ring Airy beams are experimentally generated and employed for the fabrication of
large three-dimensional structures with high resolution using multi-photon polymerization …

Bessel beams have multiple applications owing to their propagation-invariant properties,
including particle trapping, optical coherence tomography, and material processing …

In this work, we present an approach to modulate femtosecond laser beams into Bessel
beams with a spatial light modulator (SLM) for two-photon polymerization applications …

We analyze various techniques for producing a thin needle of light in which the electric field
is longitudinally polarized. We consider the use of variously polarized laser beams tightly …

We report experimental results of femtosecond laser processing on the surface of glass and
metal thin film using superposed Bessel beams. These beams are generated by a …

We report parallel two-photon photopolymerization of microgear patterns by exposing a
photoresist to holographically generated optical vortices. The optical vortices are created by …

Metal nanoclusters, which exhibit extraordinary physical and chemical properties that are
different from their bulk counterparts, are highly promising nanomaterials for photonics …

Axial resolution is one of the most important characteristics of a microscope. In all
microscopes, a high axial resolution is desired in order to discriminate information efficiently …
