Researchers developed a new type of spectral shaper that can shape the spectrum of 10,000 lines of light from a laser frequency comb. The image shows the spatial light modulator they used with a 2D ...

Ultrabroadband IR frequency comb could be used for detection in portable spectrometers. The comb uses a double-chirped mirror. Researchers at MIT have demonstrated a compact, fully integrated ...

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 ...

The search for rocky, Earth-like exoplanets has received a boost, with the arrival of a new laser frequency comb at the European Southern Observatory’s La Silla Observatory in Chile. Built by a team ...

Various applications of pulsed laser sources rely on the ability to produce a series of pulse pairs with a stepwise increasing delay between them. Implementing such optical delay scanning with high ...

An improvement to a Nobel Prize-winning technology called a frequency comb enables it to measure light pulse arrival times with greater sensitivity than was previously possible -- potentially ...

Artistic illustration of Floquet-engineered magnons: Using time as a resource, a static magnetic vortex evolves into a ...

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 ...
