High-frequency light is useful. The higher the frequency of light, the shorter its wavelength—and the shorter the wavelength, the smaller the objects and details the light can be used to see. Extreme ...

Doubling up: Georgia Tech researchers Kyu-Tae Lee (left) and Mohammad Taghinejad demonstrate frequency doubling on a slab of titanium dioxide using a red laser to create nonlinear effects with tiny ...

Menlo's optical frequency combs are a core component of optical clocks, such as this one at JILA. (Courtesy: GE Marti/JILA) This year marks the 20th anniversary of the first time an optical-frequency ...

A study carried out by a research team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the Catalan Institute of Nanoscience and Nanotechnology (ICN2), University of Exeter Centre for Graphene ...

After years of research and development, radio frequency light sources are just now becoming a mainstream lighting option. Lighting isn't exactly the first thing you think of when you hear “radio ...

TSL235R is an eternal light-to-frequency converter, and its sensors are widely used as light sensor heads in today’s advanced microcontroller projects. The TSL235R converter combines a silicon ...

OK, it's not really a black light. It's better to call it what it is: ultraviolet light. Let's start with a quick overview of light. Of course, light is an electromagnetic wave (oscillating electric ...

A revolutionary kind of laser light called an optical frequency comb makes possible a more precise type of atomic clock and many other applications Editor's note: This story was originally posted in ...

I guess it's like how we use the square root of minus one to solve various equations. It sounda impossible but actually works! Click to expand... Sort've, but I don't think they're going into the ...
