Ultrashort mid-infrared (mid-IR) laser pulses are essential for applications such as molecular spectroscopy, nonlinear microscopy, and biomedical imaging, but their generation often relies on complex ...

Ultrashort mid-infrared (mid-IR) laser pulses are essential for applications such as molecular spectroscopy, nonlinear microscopy, and biomedical ...

A compact fiber-based system has been developed to compress mid-infrared laser pulses to 187 femtoseconds using low input power. By integrating a holmium-doped ZBLAN photonic crystal fiber within a ...

Abstract: Nonlinear microscopy enables label-free imaging by deriving contrast from the intrinsic spectroscopic responses of specimens, thereby offering a valuable tool for biomedical applications.

Boron nitride is a crystalline material made of boron and nitrogen atoms arranged in a hexagonal lattice, giving it a two-dimensional structure that closely resembles graphene but with distinct ...

have found a new way to image layers of boron nitride that are only a single atom thick. This material is usually nearly invisible in optical microscopes because it has no optical resonances. To ...

Introduction: Heart failure (HF) is characterized by maladaptive changes leading to excessive fibrosis. Delineating the extent of cardiac fibrosis and its specific composition can aid in understanding ...
