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

Researchers have developed the first standard LED covering the full visible light, in collaboration with Nichia Corporation. LED and OLED lighting, which is generally called solid-state lighting (SSL) ...

(Nanowerk News) Curved lenses, like those in cameras or telescopes, are stacked in order to reduce distortions and resolve a clear image. That's why high-power microscopes are so big and telephoto ...

Integrated photonics is a rapidly-evolving industry sector, with infrared spectrum applications including high-speed 5G networks, biosensors on chip, and driverless cars. Researchers are now exploring ...

It's not easy being green. Scientists for years have made small red and blue lasers, but other colors, including green, have been a challenge. A team has now filled this technology gap by creating ...

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 ...

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 ...

For the first time ever, researchers at the US Department of Energy's Ames Laboratory have developed a material with a negative refractive index for visible light. Ames Laboratory senior physicist ...
