Mechanisms of Laser Ablation in Liquids and Their Impact on the Efficiency of Nanoparticle Generation

Laser &Photonics Reviews, EarlyView.
Laser ablation in liquid enables nanoparticle synthesis from diverse materials but remains less energy‐efficient than ablation in air. This study quantifies the absorption‐corrected ablation efficiency and experimentally confirms redeposition as the key loss mechanism using pump‐probe microscopy.

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

Laser &Photonics Reviews, EarlyView.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

High‐Sensitivity, High‐Resolution Stimulated Raman Photoacoustic Spectroscopy Enabled by Continuous‐Wave Intracavity Pump‐Stokes Beams

Laser &Photonics Reviews, EarlyView.
High‐sensitivity, high‐resolution stimulated Raman photoacoustic spectroscopy is achieved by coupling continuous‐wave pump and Stokes beams to a high‐finesse optical cavity. This approach successfully resolves the narrow Raman rotational transition S0(0) of H2 with sub‐kHz spectral resolution and attains an unprecedented sensitivity of 0.5 ppm using ...

Quad‐SPIM: A High‐Speed, Multi‐Color Light‐Sheet Microscope for 3D Imaging of Large Cleared Human Brain Tissues

Laser &Photonics Reviews, EarlyView.
A high‐speed, multi‐color light‐sheet microscope, named quad‐SPIM, enables rapid three dimensional (3D) imaging of large cleared human brain samples with simultaneous four‐channel acquisition. This custom‐built system achieves subcellular resolution across centimeter‐scale volumes, maintaining high image quality.
