Macquarie University researchers have demonstrated a technique to dramatically narrow the linewidth of a laser beam by a ...

Researchers have cracked a fundamental optical challenge: how to control both angle and wavelength of light independently—a ...

Using an advanced Monte Carlo method, Caltech researchers found a way to tame the infinite complexity of Feynman diagrams and ...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Technical University of Vienna (TU Wien) have invented a new type of tunable semiconductor laser that ...

A team at Harvard and Vienna University of Technology have invented a new tunable laser that uses a series of rings to smoothly emit many light wavelengths from a single chip. The laser could replace ...

Color light Absorption and reflection. A red object reflects red and absorbs others colors of visible light. A white - reflects waves all colors. black - absorbs all colors of visible light. Vector ...

Ray explains the origins of light, its crucial role in visibility, and how it interacts with various surfaces through reflection and refraction.

For the first time, researchers have succeeded in transforming light into a strange state of matter: the supersolid. This quantum material combines the properties of a crystalline solid and a fluid ...

Entitled, Light, Reflection, Transparency exhibition will include a vast body of artworks from as far back as the 1970s.

The article introduces a novel method for generating coherent light over an octave-spanning range at the nanoscale using phase-matching-free down-conversion in gallium selenide and niobium oxide ...
