Discover how frequency combs, specialized lasers with evenly spaced frequencies, enable precise light frequency comparison ...

The experimental setup shown here incorporates on-chip optical parametric oscillator (OPO) technology to generate a frequency comb of laser-like light covering a wide range of frequencies with very ...

In a new study published in Science, researchers have developed a new method for detecting infrared light by changing its frequency to a corresponding frequency in the range of visible light.

A team of physicists at UC Santa Barbara has seen the light, and it comes in many different colors. By aiming high- and low-frequency laser beams at a semiconductor, the researchers caused electrons ...

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 ...

New results on the interaction of femto- and attosecond light pulses with a solid insulator hold promise for reaching electronic switching rates up to the petahertz domain. Modern information ...

A novel dye-sensitized photocatalyst developed at Science Tokyo enables the capture of long-wavelength visible light for ...

LED, or light emitting diode therapy, is a skincare treatment that uses varying wavelengths of light, including red and blue. NASA originally developed it for plant growth experiments on shuttle ...

Can different colors of light really do everything from reduce wrinkles to reverse potentially cancerous sun damage? Surprisingly, the answer is yes. Decades of research has shown that different ...

Researchers develop a highly efficient method to provide coherent light of any wavelength from visible to mid-infrared with a single tiny device. (Nanowerk News) Focused laser-like light that covers a ...
