Abstract “Non‐diffracting” beams do not spread as they propagate. This property is useful in
many areas. Here, the theory, generation, properties, and applications of various “non …

A transparent variable diffractive spiral axicon (DSA) based on a single LC cell is presented.
The manufactured DSA can be switched between 24 different configurations, 12 convergent …

Optical micromanipulation is a powerful and versatile technique based upon the light–matter
interaction. Whilst the forces exerted by optical traps are naturally very small, they are …

There is an increasing need to control light phase with tailored precision via simple means
in both fundamental science and industry. One of the best candidates to achieve this goal …

Complex-shaped light fields with specially designed intensity, phase, and polarization
distributions are highly demanded for various applications including optical tweezers, laser …

Laser-based fabrication can be an alternative technology to mechanical grinding and
polishing processes. However, the performance of these elements in real applications still …

We apply femtosecond laser direct writing in photopolymers for manufacturing of conical
microlenses and closely packed arrays thereof. We demonstrate the fabrication of high …

Employing Bessel beams in imaging takes advantage of their self-reconstructing properties
to achieve small focal points while maintaining a large depth of focus. Bessel beams are …

We report on the fabrication of micro-axicons made of glass by laser-assisted wet etching
(LAE) and laser polishing. The employed technique, relying on a direct-writing process …

We propose a new design for fabrication of a highly power-efficient double axicon to
generate self-imaged three-dimensional intensity voids along the propagation of a beam …
