Noise Suppression via Gain‐Dispersion‐Managed Nonlinear Amplification in a High‐Power Er‐Fiber Laser

open access: yesLaser &Photonics Reviews, EarlyView.
Gain‐dispersion‐managed nonlinear pre‐amplification simultaneously suppresses phase and intensity noise, enabling scalable high‐power fiber amplification. The system delivers 102.3 W linearly polarized pulses with 1.19 µJ energy at 85.69 MHz and compresses them to 380 fs. Near‐linear power scaling without evident saturation highlights a practical route

Nanoscale Rear‐Interface Architecture Enables 36.2 mA cm−2 Photocurrent in Ultrathin and Bifacial ACIGS Solar Cells Through Light Management

open access: yesLaser &Photonics Reviews, EarlyView.
An array of SiOx nanopillars is developed on ITO transparent rear contacts through nanoimprint lithography to promote light scattering in 500–600 nm bifacial ACIGS solar cells. This architecture increases the short‐circuit current density by 7.8 and 7.6 mA cm−2 under front (up to 36.2 mA cm−2) and rear illumination, respectively, offering a scalable ...

Tunable TIRF Microscopy: Simultaneous Visualization of Intracellular Dynamics at Multiple Depths

open access: yesLaser &Photonics Reviews, EarlyView.
Total internal reflection fluorescence microscopy confines excitation to a thin layer, but only one depth at a time. Tunable TIRF removes this limit and assigns a different illumination depth to every region of the field of view, capturing vesicle transport and membrane dynamics simultaneously without moving mechanical parts.

Toward Low‐Power Laser Refrigeration ‐ Cooling a Resonant WGM Crystalline Cavity

open access: yesLaser &Photonics Reviews, EarlyView.
Laser refrigeration offers a method to cool solids to low temperatures by using only light. By illuminating bulk crystals doped with rare‐earth ions one can engineer the emitted fluorescent light to be at shorter wavelengths than the pump light ‐ thus extracting heat/phonons from the solid and cooling the crystals.

Impact of Monomer Purity on the Acid‐Catalyzed ROP of Sarcosine N‐Carboxyanhydrides: A Comparative Study of Phosgene‐Free Synthetic Routes toward High‐Molecular‐Weight Polysarcosine

open access: yesMacromolecular Rapid Communications, EarlyView.
A robust, phosgene‐free oxalyl chloride/silyl‐mediated route yields high‐purity sarcosine N‐carboxyanhydride (Sar‐NCA) by eliminating residual impurities that compromise polymerization control. This strategy enables well‐defined, acid‐catalyzed ring‐opening polymerization under ambient conditions, producing polysarcosine with Mn up to 186 kDa and ...

Mechanical Recycling of Hybrid Polypropylene/Recycled Carbon Fiber/Hemp Composite Wall Panels: A Comparative Study of Compression and Injection Molding

open access: yesPolymer Composites, EarlyView.
Mechanical recycling pathways for hybrid PP/rCF/hemp composite wall panels via compression and injection molding. ABSTRACT Circular economy increasingly influences sectors such as automotive, packaging, and building‐construction. The rise of circular economy in these sectors is driven by the generation of large volumes of waste that end up in landfills,
