Generation of Two‐Cycle Light Bullets With 2.0 mJ Energy via Self‐Compression of 5‐µm Pulses in Zinc Sulfide

Laser &Photonics Reviews, EarlyView.
Simultaneous temporal soliton self‐compression with simultaneous formation of a radial Townes profile is reported for millijoule pulses at 4.9 µm wavelength in ZnS. Pulses as short as 37 fs are generated in a 1‐kHz pulse train. The compression regime appears below the onset of filamentation, yielding two‐cycle pulses with 2.0 mJ energy which translates

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

Laser &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 ...

Femtosecond Laser‐Driven Fabrication of a Polymeric Lab‐on‐a‐Chip for Efficient Size‐Based Particle Sorting in a Spiral Microchannel

Macromolecular Materials and Engineering, EarlyView.
Femtosecond laser 3D micromachining enables the fabrication of spiral microfluidic devices in polymethylmethacrylate with a trapezoidal cross‐section. The process relies on scanning speed as the main control parameter, ensuring high precision and scalability.

Dual Variational Problems and Action Principles for Chen–Lee and Hopf–Langford Systems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We describe the construction of dual variational principles and action functionals for nonlinear dynamical systems using a methodology based on the dual Lagrange multiplier formalism and a convex optimization approach, to derive families of dual actions that correspond to the given nonlinear ordinary differential system.

Optimization of pseudo‐continuous arterial spin labeling for brain perfusion imaging in the intraoperative setting

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Pseudo‐continuous arterial spin labeling (PCASL) efficiency during intraoperative MRI is degraded due to large field inhomogeneities observed in some patients and lower arterial blood velocities induced by anesthesia. The purpose of this work was to maximize labeling efficiency during intraoperative MRI by optimizing PCASL parameters ...
