Comparative analysis of the DFB fiber laser and fiber-optic interferometric strain sensors

, 2007
The DFB fiber laser strain sensor is shown to provide an improvement in the minimum detectable length change by a factor of 275 at 2 kHz for an applied strain when compared with an interferometric sensor interrogated by at equivalent DFB laser.

Clinical Evaluation of the Effectiveness of Digital Peroral Cholangioscopy‐Guided Lithotripsy for Difficult Bile Duct Stones

Journal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background and Aims Peroral cholangioscopy‐guided lithotripsy (POCS‐L) has emerged as a treatment option for difficult bile duct stones (DBDSs), but detailed evidence remains limited. This study evaluated its effectiveness, safety, and risk factors for adverse events (AEs).

High‐Efficiency Phosphor Thin Films With Controlled Lateral Displacement for Low Color Crosstalk in Micro‐LED Displays

Journal of the Society for Information Display, EarlyView.
High‐efficiency nano‐phosphor thin films were developed for micro‐LED color conversion, achieving high quantum efficiency and reduced lateral photon displacement. The optimized film structure effectively suppresses color crosstalk and enables high‐performance, full‐color micro‐LED displays.

Ambient‐Light‐Activated Rewritable Optical Patterning in Transparent Long‐Afterglow Garnet Ceramics

Laser &Photonics Reviews, EarlyView.
This work demonstrates sunlight‐activated rewritable optical information storage in transparent long‐afterglow Y3Al2Ga3O12:Ce (YAGG:Ce) garnet ceramics fabricated via solid‐state sintering with tetraethyl orthosilicate (TEOS) as a sintering aid. By integrating ambient‐light operability, reversibility, and high optical clarity in a robust ceramic host ...

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

Lasers 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).

Synthesis and Characterization of an Azido Nitrofurazanyl Ether: An Energy‐Rich Heterocyclic Plasticizer With a Low Glass Transition Temperature

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT We report on the synthesis and characterization of 3‐(2‐(2‐azidoethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG2N3), which is a liquid nitrofurazanyl ether that was designed to be an energy‐rich plasticizer for glycidyl azide polymer (GAP)‐ and nitrocellulose (NC)‐based formulations.
