Ultrafast laser processing creates silicon surfaces that absorb nearly all infrared light and remain stable under heat and wear, enabling coating-free infrared sensing and calibration. (Nanowerk ...

Lasers that emit near-infrared light are important for many applications, from optical telecommunications to biomedical imaging. If they could be built out of organic molecules, they’d be cheaper and ...

A new way to make broadband white light using a cheap, portable infrared diode laser has been developed by researchers in Germany. The technology uses nonlinear effects in a specially designed, easily ...

Probing the deep structure of atoms, molecules, and solids often requires X-rays. The energies and wavelengths of X-ray light are ideal for examining electronic spin properties, chemical details, and ...

Lasers are known to be a high energy and high-temperature heat source. Whilst most of their use is in various optics applications, there are a couple of lasers which are used in heat treatment ...

Scientists in the US are the first to combine infrared and X-ray lasers to study the electronic properties of matter. The technique involves firing infrared light at a diamond sample that is also ...

When a laser experiment fails to produce the expected flash of light, most researchers would assume something went wrong with ...
