Optical coherence extends beyond lasers, with partially coherent light enhancing imaging, communication, and photonic ...

X-ray free-electron lasers produce pulses of light that are exceptionally bright, making them powerful tools for studying ultrafast chemical reactions, biological processes, or probing the structure ...

Owing to the wave nature of light there are many ways that such different waves can interact with each other, but also with materials. Everyone knows about reflecting light with a mirror, which is a ...

Knots and links, with their unique and robust topological structures, play a vital role across various disciplines, including physics, life sciences, and light–matter interactions. As a representative ...

Nonlinear optics has long relied on high-power lasers, whose spatial and temporal coherence ensures efficient nonlinear frequency conversion. However, a new study challenges the traditional assumption ...

Researchers have developed a new imaging technique that captures more information about ultrafast processes in the microscopic world than was previously possible. The technique offers scientists a ...
