Customized Scattering‐Robust 3D Speckle Correlation for Improved Resolution and Imaging Depth in Scattering Tissue

open access: yesLaser &Photonics Reviews, EarlyView.
A scattering‐robust 3D speckle customization method is proposed to enhance both resolution and imaging depth in scattering tissue. Applied to light‐field microscopy (LFM), it improves 3D resolution by over twofold under strong optical scattering. In wide‐field fluorescence imaging, it enables a substantial improvement in imaging depth, allowing imaging

Enhanced Dichroic Coloration Through Void‐Particle Induced Interference in Randomly Distributed Cu2O Octahedrons on Glass Substrate

open access: yesLaser &Photonics Reviews, EarlyView.
In randomly distributed Cu2O octahedron particles on a glass substrate, the absence of particles in certain areas generates a distinct “void‐particle induced interference” phenomenon. This effect results in notable reflection and transmission dichroism, characterized by two reflection peaks within the visible spectrum, but only a single transmission ...

Dispersion‐Less Dissipative Soliton Fiber Laser

open access: yesLaser &Photonics Reviews, EarlyView.
A dispersion‐less fiber laser architecture generates high‐energy, pedestal‐free picosecond pulses without resorting to conventional pulse stretching. This energy‐managed laser achieves remarkable flexibility in pulse parameters, delivering up to 0.54 μJ$\mathrm{\mu}\mathrm{J}$ pulses with minimal spectral distortion using standard telecom components ...

Time‐Stretched Interferometric LiDAR with Dispersive Wavenumber‐to‐Time Range Encoding

open access: yesLaser &Photonics Reviews, EarlyView.
We present a time‐stretched interferometric LiDAR that directly encodes distance into time‐domain interference signals. Operating at 5 MHz with only millimeter‐level coherence length, the system measures up to 12 m with centimeter precision and resolution, achieving high‐speed 3D imaging and dynamic target detection without FFT processing or long ...
