DOI: 10.1364/oe.419486
Abstract: Many applications ranging from nonlinear optics to material processing would benefit from pulsed ultrashort (quasi-)non-diffracting Gauss-Bessel beams (GBBs). Here we demonstrate a straightforward yet efficient method for generating such zeroth- and first-order GBBs using a… read more here.

DOI: 10.1364/ol.486214
Abstract: Sub-diffraction-limit quasi-non-diffracting light sheets (SQLSs) are crucial for a resolution-enhanced and field of view (FOV)-enlarged light sheet microscope. However, it has aways been plagued by sidelobes inducing severe background noise. Here, a self-trade-off optimized method… read more here.

DOI: 10.1364/ome.431315
Abstract: Multiform electromagnetic beams (multi-direction, multi-polarization, multi-frequency, and multi-beam) generated by ultrathin metasurfaces show promising prospects in multiple optical traps, modern communication systems, and identification in complex environments. However, their application is limited by their inability… read more here.
