Optics & Photonics

Laser systems operating in the 2-micrometer wavelength range open diverse opportunities in medical technology, agriculture, and plastics processing. In the Eurostars project DECOMP, Laser Zentrum Hannover e.V. (LZH) has developed…

Quantum entanglement is a state in which particles are entwined with each other. In this entwined state, the properties of one particle influence the other, even when they aren't physically…

Nonlinear interactions between light and matter are at the heart of some of the most powerful tools in modern optics, but pushing these processes to their limits has long been…

A research group led by Assistant Professor Takafumi Tomita and Professor Kenji Ohmori at the Institute for Molecular Science, National Institutes of Natural Sciences, has developed a new microscopy technique…

An extremely fast microscopy method to research the interaction of light and matter makes it possible to study optical processes on very short timescales. To this end, a German–Italian research…

Physicists from Emory University have led work to develop a microscopic, nonlinear light source that can be switched on, off or tuned to a particular intensity by an electrical "knob."…

Spectroscopy has many applications, ranging from fundamental tests of quantum electrodynamics and investigations of molecular structure to environmental sensing, biomedical diagnostics and industrial monitoring. A highly promising spectroscopic instrument that…

Solar panels have become more efficient over the years, but even the best designs still lose a large fraction of the energy they absorb. Scientists around the world have been…

When a singer belts out a tune while a guitar player strums along, sound waves travel through the air, driving collective oscillations of the molecules within. Meanwhile, at the quantum…

Being able to see light and detect radiation is of utmost importance at any frequency. While this challenge has been solved in the visible range, radiation detectors in the far-infrared…
