The field of 3D micro‐optics is rapidly expanding, and essential advances in femtosecond
laser direct‐write 3D multi‐photon lithography (MPL, also known as two‐photon or multi …

Optical tweezers, a simple and robust implementation of optical micromanipulation
technologies, have become a standard tool in biological, medical and physics research …

Nonlinear wavefront sha** in periodically poled ferroelectric crystals has received great
attention because it offers a convenient way to generate a structured light beam at new …

Three-dimensional (3D) microstructures used in the formation of optical traps on the optical
axis in the near diffraction zone are calculated and studied. Subwavelength, variable-height …

It is demonstrated how structured laser beams can be used to implement holographic optical
tweezers for trap** and manipulating light-absorbing nano-and microparticles in the air …

A new type of off‐axis and multi optical bottle (OB) from an astigmatic‐phase ring Airy
Gaussian vortex beam (APRAGVB) propagating in free space is derived numerically. By …

We investigate the formation of single and multiple optical bottle beams on the optical axis
using a diffractive axicon with amplitude or phase apodization. The proposed approach …
