Mitigation of transverse mode instability in polarization maintaining, high-power fiber amplifiers

, 2021
Paper 116650V, 6 S.A new passive mitigation strategy for the effect of transverse mode instability is presented in this work. This technique requires the use of a polarization-maintaining fiber in which light is coupled with a polarization state oriented

Extracellular matrix remodeling and immune reprogramming drive residual tumor progression of liver cancer after incomplete microwave ablation

Molecular Oncology, EarlyView.
Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

Components and tools for polarization‐maintaining fiber optics [PDF]

Laser Technik Journal, 2012
AbstractFiber cables open up new vistas for the design of modular devices and compact setups for industrial and scientific applications. Special fibers, such as polarization‐maintaining singlemode fibers, are predestined for use in complex, self‐contained setups, increasing laser safety by reducing the laser safety classification.

KDAC6 alters cell morphology and motility through positive and negative modulation of F‐actin distribution

FEBS Open Bio, EarlyView.
KDAC6 has been associated with cell motility and actin structures, but specific domain contributions are not established. The two catalytic domains have differential effects on motility and F‐actin regulation, affecting cortical F‐actin density, motility, stress fibers, and cell spreading.

Single-polarization laser operation in polarization-maintaining single-polarization pumped erbium-doped fiber [PDF]

, 2001
We demonstrate a linearly polarized fiber laser in a polarization-maintaining erbium-doped fiber pumped by linearly polarized light. The laser output polarization followed the pump polarization when this was aligned on either of the fiber's principal ...
