The ultrabroadband infrared frequency comb could be used for chemical detection in portable spectrometers or high-resolution remote sensors. (Nanowerk News) Optical frequency combs are specially ...

Cambridge, MA – Optical frequency combs are specially designed lasers that act like rulers to accurately and rapidly measure specific frequencies of light. They can be used to detect and identify ...

The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can’t see, has an even lower frequency than ...

Researchers have for the first time demonstrated that a specific class of oxide membranes can confine, or 'squeeze,' infrared light -- a finding that holds promise for next generation infrared imaging ...

From left to right: Schematic of the nonlinear optical mirror used for up-conversion imaging. Energy diagram showing the sum frequency generation process used for up-conversion. Representative ...

While a single X-ray photon is more energetic, low-frequency laser fields allow for a multi-photon interaction. During a ...
