How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many applications, for instance, quality control of manufacturing semiconductor ...

A study demonstrates that graphene-based materials can be used to efficiently convert high-frequency signals into visible light, and that this mechanism is ultrafast and tunable. These outcomes open ...

The exoplanet 51 Pegasi b lies some 50 light-years from Earth in the constellation of Pegasus. It was discovered in 1995 and will forever be remembered as the first confirmed exoplanet to be found ...

Researchers in Quebec, Canda, have developed the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum. Fiber lasers producing ultrashort, bright ...
