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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Laser-like light that spans a wide range of frequencies is a powerful tool for science and industry. From semiconductor chip ...

A new, miniature laser source developed by applied physicists in the Harvard John A. Paulson School of Engineering and ...

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 ...

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 tunable metasurface can control optical light in space and time, offering a path toward new ways of wirelessly and securely transmitting large amounts of data both on Earth and in space. It is a ...

Researchers report their insights on the emerging field of complex frequencies excitations, a recently introduced scheme to control light, sound and other wave phenomena beyond conventional limits.

IT is the purpose of this note to direct attention to the importance of a recent experiment 1 on the constancy, with time, of the frequency of light from an emitting atom, from the point of view of ...

Medical device company EmitBio is testing a device that uses precise light frequencies it claims can keep the coronavirus at bay. The best weapon in the fight against the Covid-19 pandemic remains the ...

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 ...

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 ...
