The light propagation in the medium normally experiences diffraction, dispersion, and
scattering. Studying the light propagation is a century-old problem as the photons may …

We explore the potential of twisted light, a structured beam carrying orbital angular
momentum, as a tool to unveil many-body effects in parabolically confined systems …

Non‐diffraction electromagnetic beams such as Airy beams attract wide exploration in
various disciplines owing to its fascinating features and great potential of applications …

Intravital microscopy in small animals growingly contributes to the visualization of short-and
long-term mammalian biological processes. Miniaturized fluorescence microscopy has …

We have demonstrated the background-free volumetric two-photon microscopy by
cancelling the side lobes of the fundamental 0th-order Bessel beam. The cancellation is …

All-optical photoacoustic microscopy (AOPAM) facilitates high-sensitivity, wide-bandwidth,
volumetric imaging without coupling media. However, the rapid divergence of the Gaussian …

Optical fabrication of waveguides in a volume is limited by diffraction in the writing beams.
We demonstrate the use of nondiffracting waves in the form of Bessel beams to fabricate …
