Grating‐Lens Empowered Metafiber for Large‐Angle Light Collection With 3D Nanoprinted Structures

open access: yesLaser &Photonics Reviews, EarlyView.
A grating‐lens‐based Metafiber enables efficient light coupling into single‐mode fibers at large incidence angles. By combining diffraction and focusing on the fiber facet using a 3D nanoprinted holographic structure, light is selectively coupled only at specific angles while suppressing unwanted signals. This approach achieves high coupling efficiency

Harnessing Optical Limiting in Saturable Absorbers for Reconfigurable Spectral Engineering of Ultrafast Fiber Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
Optical limiting in a nanomaterial‐polymer saturable absorber is harnessed as a functional intracavity degree of freedom, where pump‐controlled photothermal loss continuously reshapes the gain spectrum of rare‐earth ions, enabling non‐mechanical spectral engineering in an ultrafast fiber laser.

Phase Multiplexed Optical Computing: Reconfiguring a Multi‐Task Diffractive Optical Processor Using Illumination Phase Diversity

open access: yesLaser &Photonics Reviews, EarlyView.
A monochrome multi‐task diffractive optical network architecture is designed to leverage illumination‐phase multiplexing to dynamically reconfigure its output function and accurately implement a large set of complex‐valued linear transformations between an input and an output aperture.

Use of Simultaneous Emission of Nd:YAG and Alexandrite Lasers in BLEND Mode for Hair Removal and Permanent Hair Reduction

open access: yesLasers in Surgery and Medicine, EarlyView.
Abstract Objective To evaluate the safety, efficacy, and patient satisfaction of a novel laser technology that employs simultaneous emission of Alexandrite (755 nm) and Nd:YAG (1064 nm) wavelengths for permanent hair removal, as compared with standard of care treatment using a single wavelength (either Alexandrite or Nd:Yag).
