Laser pulse control of a Q-switched Nd:YVO4 bounce geometry laser using a secondary cavity

open access: yes
Pulsed laser operation is desirable for a wide range of applications such as laser micromachining in industrial manufacturing and laser marking for product identification. In these cases it is beneficial to have flexibility in the parameters of the laser

Kinetic Regimes of Hydrogen Absorption in Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Knowledge of the hydrogen incorporation mechanisms in thin layers in relation to the amount absorbed is essential to design coatings and devices compatible with hydrogen‐based technologies. A combination of simultaneous in situ methods gives detailed insight into the hydrogenation of a prototypical hydrogen absorber layer in a time‐dependent manner ...

Unlocking Photodetection Mode Switching from a Simple Lateral Design

open access: yesAdvanced Functional Materials, EarlyView.
A simple lateral 2D perovskite photodetector capable of switching among transient, continuous, and dual transient/continuous photoresponse modes is achieved by integrating photoconductive effects with capacitive coupling from the SiO2/Si substrate. Such light‐programmable photodetection mode switching enables triple‐channel information transmission and

Impact of energy-transfer-upconversion on the performance of hybrid Er:YAG lasers

open access: yes
Using a hybrid fiber-bulk laser scheme based on Er:YAG, we have achieved ~60 W and ~30 W of continuous-wave output at 1645nm and 1617nm respectively, and Q-switched pulse energies up to ~30 mJ (limited by coating damage). Investigation of various factors

Magnetothermal‐Triggered Response and Self‐Healing of Recyclable and Reprocessable Nanocomposites for Actuation Systems

open access: yesAdvanced Functional Materials, EarlyView.
Developing recyclable materials for magnetic robotics that combine rapid response and self‐healing properties is challenging. Hence, this study focuses on the integration of magnetothermal nanoparticles into a dynamic sorbitol‐based vitrimer, a recyclable composite capable of remote actuation and self‐healing by magnetic heating.

Structural and Chemical Engineering of Sub‐Nanochannel Membranes Toward Ion Selectivity

open access: yesAdvanced Functional Materials, EarlyView.
This review summarizes recent advances in structural and chemical engineering of sub‐nanochannels for ion selectivity. We first introduce fundamental ion transport mechanisms within sub‐nanochannels, followed by strategies to tune pore size, geometry, and surface functionalities, categorized into charge‐based, ion‐recognition, hydrophilic bonding, and ...

Q-Switching Nanophotonic Biosensing

open access: yes
Abstract Sensitive, label-free detection of biomarkers is critical for clinical diagnostics. However, conventional nanophotonic biosensors, typically based on single-oscillator architectures, remain confined to either real or imaginary sensing domain. This isolation often results in weak signal responses, limited operational stability, and high
