Structured light refers to the ability to tailor optical patterns in all its degrees of freedom, from
conventional 2D transverse patterns to exotic forms of 3D, 4D, and even higher-dimensional …

We report a novel method to freely transform the modes of a perfect optical vortex (POV). By
adjusting the scaling factor of the Bessel–Gauss beam at the object plane, the POV mode …

We originally exploit the vortex beams with patterns of closed polygons [namely, polygonal
vortex beams (PVBs)] generated by a quasi-frequency-degenerate (QFD) Yb: CALGO laser …

For optical tweezers, a tiny focal spot of the trapping beam is necessary for providing
sufficient intensity-gradient force. This condition results in a limited small trapping range to …

Laguerre-Gaussian (LG) beams contain a helical phase front with a doughnut-like intensity
profile. We use the LG beam to introduce a rather simple method for generation of a vector …

The perfect optical vortex (POV) beam carrying orbital angular momentum with topological
charge-independent radial intensity distribution possesses ubiquitous applications in optical …

Compared with the on-axis vortex beam and the off-axis single vortex beam, the off-axis
double vortex beam has more control degrees of freedom and brings rich physical …

This study demonstrates a method for microparticle optical trapping of silica gel using a
stable Q-switched fiber laser (QFL) pulse. Gold nanoparticle (Au-NP) were fabricated as …

We analyze the optical radiation forces, produced by a focused rotational elliptical Laguerre–
Gaussian correlated Schell-model (ELGSM) beam, on the dielectric particles of different …

Optical evanescent wave in total internal reflection has been widely used in efficient optical
manipulation, where the object is trapped by the intrinsic intensity gradient of the evanescent …
